Nursing Elites

1. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?

• A. None; absorption of the second drug is not affected.
• B. The increased gut motility decreases the absorption of the second drug.
• C. The absorption of the second drug cannot be predicted.
• D. Less of the second drug is absorbed.

Correct answer: D

Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.

2. 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.

3. Which of the following lab values would indicate symptomatic AIDS in the medical chart? (T4 cell count per deciliter)

• A. Greater than 1000 cells per deciliter
• B. Less than 500 cells per deciliter
• C. Greater than 2000 cells per deciliter
• D. Less than 200 cells per deciliter

Correct answer: D

Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.

4. Which infection control measure is the priority for the nurse to implement in the care provided for a child admitted to the hospital with bacterial meningitis?

• A. Place the child in a private room
• B. Gowns and masks must be worn by all personnel in the child's room
• C. Visitors are restricted to parents only
• D. Hand washing is required by all personnel and visitors having contact with the child

Correct answer: B

Rationale: The priority control measure for the nurse to implement in caring for a child with bacterial meningitis is ensuring that gowns and masks are worn by all personnel in the child's room. This measure is crucial as the child with bacterial meningitis is contagious for at least 24 hours after starting antibiotics, necessitating airborne precautions to prevent the spread of infection to healthcare workers and other patients. Placing the child in a private room (Choice A) is important but secondary to preventing infection transmission. Restricting visitors to parents only (Choice C) is also significant but not as critical as ensuring proper infection control measures. While hand washing (Choice D) is essential, the immediate need to prevent airborne transmission in the child's room takes precedence.

5. During a home health visit, a nurse consults with a male patient diagnosed with CAD and COPD who is taking Ventolin, Azmacort, Aspirin, and Theophylline and complains of upset stomach, nausea, and discomfort. What should the nurse do?

• A. Contact the patient's physician immediately
• B. Recommend the patient lie on his right side
• C. Advise the patient to schedule a doctor's visit the next day
• D. Suggest holding the drug Azmacort

Correct answer: A

Rationale: The correct answer is to contact the patient's physician immediately. The patient's symptoms of upset stomach, nausea, and discomfort could indicate theophylline toxicity, a potentially serious condition. It is crucial to consult the physician promptly to address this issue. Option B, recommending the patient lie on his right side, is incorrect as it does not address the potential theophylline toxicity and is not a priority. Option C, advising the patient to schedule a doctor's visit the next day, is inappropriate as the symptoms may indicate an urgent concern. Option D, suggesting holding the drug Azmacort, is incorrect as it does not address the potential theophylline toxicity and should not be done without consulting the physician first.
