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. Is head lag expected to be resolved by 4 months of age? Continuing head lag at 6 months of age may indicate?

• A. Dizziness and orthostatic hypotension.
• B. Nausea, vomiting, diarrhea, or constipation, and stomach cramps.
• C. Drowsiness, lethargy, and fatigue.
• D. Neuropathy and tingling in the extremities.

Correct answer: B

Rationale: Head lag is a developmental milestone that should be resolved by 4 months of age. Continuing head lag at 6 months of age may indicate potential developmental delays or muscle weakness. The correct answer, 'Nausea, vomiting, diarrhea, or constipation, and stomach cramps,' reflects symptoms that could be associated with developmental delays or underlying health conditions. Dizziness and orthostatic hypotension (Choice A) are unlikely to be directly related to head lag. Choices C and D present symptoms that are unrelated to the issue of continued head lag at 6 months of age.

4. What is appropriate care for a client with neutropenia?

• A. Avoiding fresh fruits and vegetables.
• B. Having a private room.
• C. Wearing a mask when out of the room.
• D. Practicing routine hand washing.

Correct answer: C

Rationale: When a client has neutropenia, they have low white blood cell levels, which increases the risk of infections due to a weakened immune system. Wearing a mask when out of the room is crucial to reduce the risk of exposure to respiratory infections. Avoiding fresh fruits and vegetables is also necessary as they may contain harmful pathogens. Having a private room helps minimize exposure to pathogens and ensures that visitors are carefully screened for any signs of illness. Routine hand washing is essential to prevent the spread of infections in the healthcare setting, but the most direct measure to protect the client from potential infections is wearing a mask when out of the room.

5. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.
