Nursing Elites

1. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

2. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?

• A. Use a soft toothbrush.
• B. Use dental floss daily.
• C. Hold pressure on any scrapes for 1-2 minutes.
• D. Use a triple-edged razor.

Correct answer: A

Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.

3. The client develops a tension pneumothorax. Assessment is expected to reveal?

• A. Sudden hypertension and bradycardia
• B. Productive cough with yellow mucus
• C. Tracheal deviation and dyspnea
• D. Sudden development of profuse hemoptysis and weakness

Correct answer: C

Rationale: In a tension pneumothorax, the trachea deviates to the unaffected side due to increased pressure in the affected pleural space, causing respiratory distress. Dyspnea is a hallmark symptom as the lung on the affected side collapses, leading to difficulty in breathing. Sudden hypertension and bradycardia (Choice A) are not typical findings of tension pneumothorax. Productive cough with yellow mucus (Choice B) is more suggestive of respiratory infections rather than a tension pneumothorax. Sudden development of profuse hemoptysis and weakness (Choice D) is not characteristic of tension pneumothorax presentation.

4. High uric acid levels can develop in clients who are receiving chemotherapy. This can be caused by:

• A. the inability of the kidneys to excrete the drug metabolites.
• B. rapid cell catabolism.
• C. toxic effects of the prophylactic antibiotics that are given concurrently.
• D. the altered blood pH from the acidic nature of the drugs.

Correct answer: B

Rationale: The correct answer is 'rapid cell catabolism.' During chemotherapy, rapid cell destruction occurs, leading to an increase in uric acid levels as a byproduct of cell breakdown. High uric acid levels are primarily a result of the rapid breakdown of cells during chemotherapy, not due to the kidneys' inability to excrete drug metabolites (Choice A). The prophylactic antibiotics given concurrently do not directly cause high uric acid levels (Choice C). The altered blood pH from the acidic nature of the drugs (Choice D) is not a direct cause of elevated uric acid levels; the main mechanism is the rapid cell catabolism that occurs during chemotherapy.

5. The nurse teaching about preventable diseases should emphasize the importance of getting the following vaccines:

• A. human papillomavirus, genital herpes, measles.
• B. pneumonia, HIV, mumps.
• C. syphilis, gonorrhea, pneumonia.
• D. polio, pertussis, measles.

Correct answer: D

Rationale: Vaccines are one of the most effective methods of preventing and controlling certain communicable diseases. The smallpox vaccine is not currently in use because the smallpox virus has been declared eradicated from the world's population. Diseases such as polio, diphtheria, pertussis, and measles are mostly controlled by routine childhood immunization. They have not, however, been eradicated, so children need to be immunized against these diseases. Choices A, B, and C contain vaccines that do not protect against preventable diseases like polio, pertussis, and measles. Therefore, the correct choice is D.
