Question 55 of 108
Which of the following conditions is suspected?
Select an option. Use Strike to cross one out.
Rationale
Option C: Leukemia is suspected due to its association with abnormal blood cell production, leading to symptoms such as fatigue, frequent infections, and easy bruising. These clinical manifestations are critical in identifying leukemia, which requires prompt diagnosis and management.
Option A: Anemia typically presents with fatigue and pallor but does not account for the increased risk of infections or bleeding associated with leukemia. Thus, it lacks the specific symptoms indicative of leukemia.
Option B: Rheumatic arthritis primarily affects joints and is characterized by pain and swelling, not the hematological abnormalities seen in leukemia. The symptom profile does not align with the suspicion of leukemia.
Option D: Systemic Lupus Erythematosus (SLE) presents with a variety of systemic symptoms, including joint pain and skin rashes, but lacks the specific hematological findings that would suggest leukemia. This makes it an unlikely condition in this context.
Takeaways: Understanding the clinical presentation of leukemia, including symptoms like fatigue and increased susceptibility to infections, is essential for accurate diagnosis and management. For more information on leukemia symptoms and treatment, see Leukemia Information from MedlinePlus.

A patient visits her nurse practitioner (NP) after she has a cold for a week and is now experiencing a severe headache and fever. Her NP diagnoses a sinus infection. Which of the following additional symptoms is the patient likely to exhibit?
Select an option. Use Strike to cross one out.
Rationale
Option A: Facial tenderness is a common symptom associated with sinus infections, resulting from inflammation and pressure in the sinus cavities. This tenderness often occurs around the cheeks, forehead, and eyes, making it a likely additional symptom for the patient experiencing a sinus infection.
Option B: Photophobia is typically associated with conditions like migraines or meningitis rather than sinus infections. While headaches can occur, photophobia is not a classic symptom of sinusitis.
Option C: Chest pain is not a typical symptom of sinus infections. It may indicate other conditions such as respiratory issues or cardiac problems, which are not directly related to sinusitis.
Option D: Ear drainage can occur with some ear infections but is not a common symptom of sinus infections. Sinusitis primarily affects the nasal passages and sinuses rather than the ears directly.
Takeaways: Facial tenderness is a hallmark symptom of sinus infections due to inflammation in the sinus cavities, which can lead to discomfort and pressure. Understanding these symptoms is crucial for accurate diagnosis and management of sinusitis, as outlined in this resource on sinusitis symptoms.

Calcium carbonate is given with meals to a child with chronic renal disease. What is the purpose of administering calcium carbonate?
Select an option. Use Strike to cross one out.
Rationale
Option B: Bind phosphorus. Calcium carbonate is administered with meals to bind dietary phosphorus in patients with chronic renal disease, helping to manage hyperphosphatemia, which is common in this population due to impaired renal function.
Option A: Prevent vomiting. Calcium carbonate does not have a primary role in preventing vomiting; its main function is to bind phosphorus.
Option C: Stimulate appetite. There is no evidence that calcium carbonate stimulates appetite; its purpose is related to phosphorus binding.
Option D: Increase absorption of fat-soluble vitamins. Calcium carbonate does not enhance the absorption of fat-soluble vitamins; its role is specifically in managing phosphorus levels in the body.
Takeaways: Calcium carbonate is used in chronic renal disease primarily to bind phosphorus and manage hyperphosphatemia, which requires dietary management and monitoring to prevent complications associated with renal failure.

Question 58 of 108
What is cellulitis often caused by?
Select an option. Use Strike to cross one out.
Rationale
Option D: Streptococcus or Staphylococcus organisms are the primary causative agents of cellulitis, a common bacterial skin infection. These organisms typically enter through breaks in the skin, leading to inflammation, redness, and swelling, which are characteristic of cellulitis.
Option A: Herpes zoster, the virus responsible for shingles, does not cause cellulitis. Instead, it leads to a painful rash and blisters, primarily affecting dermatomes rather than causing widespread skin infection.
Option B: Candida albicans is a fungus that causes infections such as candidiasis, not cellulitis. It typically affects mucosal surfaces and skin folds but does not lead to the bacterial infection associated with cellulitis.
Option C: Human papillomavirus (HPV) is associated with warts and certain cancers, not cellulitis. It does not cause bacterial skin infections and is unrelated to the inflammatory process seen in cellulitis.
Takeaways: Cellulitis is primarily caused by bacterial organisms, specifically Streptococcus and Staphylococcus, which require prompt medical treatment to prevent complications and further spread of infection.

Question 59 of 108
which of the following is a characteristic in a child with acute lymphocytic leukemia?
Select an option. Use Strike to cross one out.
Rationale
Option D: all of the above are correct. Children with acute lymphocytic leukemia (ALL) commonly present with symptoms such as fatigability, persistent fever of unknown cause, and a tendency to bruise easily due to bone marrow infiltration and resultant cytopenias. These manifestations highlight the systemic effects of the disease on hematopoiesis and immune function.
Option A: fatigability is a common symptom in children with ALL, resulting from anemia and the body's increased energy demands in response to the disease. However, it does not encompass the full range of symptoms associated with ALL.
Option B: persistent fever of unknown cause can occur in ALL due to leukemic infiltration and immune dysregulation, but it is only one of several symptoms present in the disease.
Option C: tendency to bruise easily stems from thrombocytopenia, which is characteristic of ALL, yet it does not represent the entirety of the clinical picture.
Takeaways: All symptoms listed—fatigability, persistent fever of unknown cause, and tendency to bruise easily—are indicative of acute lymphocytic leukemia in children, emphasizing the need for comprehensive evaluation in suspected cases. For further details on symptoms and management, refer to MedlinePlus on leukemia.

Question 60 of 108
Which of the following chromosomal abnormalities of childhood ALL carries the highest risk of relapse despite intensive chemotherapy?
Select an option. Use Strike to cross one out.
Rationale
Option A: t(9;22) is associated with Philadelphia chromosome-positive acute lymphoblastic leukemia (ALL), which carries the highest risk of relapse despite intensive chemotherapy due to its resistance to standard treatment and poorer overall prognosis compared to other genetic abnormalities.
Option B: t(4;11) is linked to a specific subtype of ALL, but it does not carry the same high relapse risk as t(9;22). While it is associated with a poor prognosis, it is not the highest risk.
Option C: hypodiploidy indicates a lower number of chromosomes and is associated with a poor prognosis; however, it does not have the same specific association with relapse risk as t(9;22).
Option D: t(1;19) is a rearrangement found in some cases of ALL, but it does not carry the highest risk of relapse compared to t(9;22), which is more notorious for its treatment resistance.
Takeaways: The t(9;22) chromosomal abnormality in childhood ALL is linked to a significantly higher risk of relapse despite intensive chemotherapy, necessitating targeted therapies and close monitoring for effective management.

Question 61 of 108
Which of the ff actions should the nurse perform before a client with impaired physical mobility gets up?
Select an option. Use Strike to cross one out.
Rationale
Option A: Use parallel bars or a walker is essential for providing stability and support to clients with impaired physical mobility before they attempt to stand or walk. This action helps prevent falls and promotes safe ambulation by ensuring the client has adequate assistance and balance support.
Option B: Use incontinence pads does not address the immediate safety needs of a client with impaired mobility. While incontinence management is important, it does not provide the necessary support for standing or walking.
Option C: Apply an abdominal binder is not relevant to the immediate action of assisting a client with mobility issues. An abdominal binder may be used for support in specific conditions but does not aid in ambulation safety.
Option D: Use a footboard does not assist with the act of getting up or walking. A footboard may help with positioning in bed but does not provide the necessary support for ambulation.
Takeaways: Ensuring client safety during ambulation requires the use of supportive devices like walkers or parallel bars, which are crucial for preventing falls and promoting mobility in patients with physical impairments.

Question 62 of 108
When administering oxygen to a client, under which of the ff situations should the nurse discontinue the administration and notify the physician?
Select an option. Use Strike to cross one out.
Rationale
Option C: When the client is in a state of respiratory arrest, oxygen administration should be discontinued, and the physician notified immediately. In respiratory arrest, the client is not breathing effectively, and oxygen will not be beneficial without airway management and resuscitation efforts.
Option A: When the client's color does not improve, this may indicate inadequate oxygenation; however, oxygen should not be stopped without further assessment and intervention.
Option B: A decrease in the client's level of consciousness can signify worsening hypoxia or other critical conditions. Oxygen should be continued while further evaluation is conducted.
Option D: If the client cannot effectively use the diaphragm, this indicates a potential respiratory issue, but oxygen should still be provided while addressing the underlying cause.
Takeaways: Discontinuation of oxygen therapy is warranted in critical situations like respiratory arrest, where immediate medical intervention is necessary to restore breathing and oxygenation. Proper assessment and monitoring are essential in managing clients requiring oxygen therapy, as outlined in this resource on oxygen therapy management.

Question 63 of 108
When palpating the brachial, radial, and femoral pulses of a neonate, the nurse notes a difference in pulse amplitude between the femoral and radial pulses bilaterally. This difference suggests:
Select an option. Use Strike to cross one out.
Rationale
Option B: A difference in pulse amplitude between the femoral and radial pulses in a neonate suggests coarctation of the aorta, a condition where there is a narrowing of the aorta, typically distal to the left subclavian artery. This leads to decreased blood flow to the lower body, resulting in weaker femoral pulses compared to the radial pulses.
Option A: Patent ductus arteriosus typically presents with bounding pulses and does not usually cause a significant difference in pulse amplitude between the upper and lower extremities.
Option C: Diminished cardiac output can lead to weak pulses overall, but it does not specifically explain the differential between femoral and radial pulses.
Option D: Left to right shunting in the heart generally results in increased blood flow to the lungs and does not create a disparity in pulse strength between the upper and lower extremities.
Takeaways: The presence of a differential in pulse amplitude between the femoral and radial pulses indicates potential coarctation of the aorta, necessitating further evaluation and management to prevent complications such as hypertension and heart failure. For more information on this condition, see coarctation of the aorta.
