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. The healthcare provider should utilize data about which of the following to provide information about the nutritional status of a client being evaluated for malnutrition?

• A. triceps skinfold measurement
• B. fasting blood glucose level
• C. hemoglobin A1c level
• D. serum lipid profile results

Correct answer: A

Rationale: Objective anthropometric measurements such as triceps skinfold and mid-arm circumference (MAC), along with weight, are usually used to diagnose malnutrition. Triceps skinfold measurement specifically helps assess body fat and muscle mass, providing valuable information about the client's nutritional status. Fasting blood glucose level, hemoglobin A1c level, and serum lipid profile results are important tests in assessing different aspects of health such as diabetes management and cardiovascular risk, but they are not specific indicators of malnutrition.

3. A mother of a newborn notices a nurse placing liquid in her baby's eyes. Which of the following is an inaccurate statement about the need for eyedrops following birth?

• A. Eyedrops following birth help reduce the risk of eye infection.
• B. Eyedrops are required by law.
• C. Eyedrops will keep the eye moist.
• D. Eyedrops are required by law every 6 hours following birth.

Correct answer: D

Rationale: The correct answer is 'Eyedrops are required by law every 6 hours following birth.' This statement is inaccurate because while laws do require the placement of eyedrops, physicians indicate a specific timeframe for their administration. Choice A is correct because eyedrops following birth do help reduce the risk of eye infection by preventing ophthalmia neonatorum. Choice B is incorrect as it implies that eyedrops are mandated solely by law, without considering medical reasons. Choice C is accurate as eyedrops do help keep the eye moist, preventing dryness and discomfort.

4. A nurse is caring for a client with an elevated urine osmolarity. The nurse should assess the client for:

• A. fluid volume excess.
• B. hyperkalemia.
• C. hypercalcemia.
• D. fluid volume deficit.

Correct answer: D

Rationale: Elevated urine osmolarity indicates that the urine is concentrated, suggesting the body is trying to conserve water. This commonly occurs in conditions like dehydration or fluid volume deficit. Assessing the client for fluid volume excess, hyperkalemia, or hypercalcemia would not be the priority in this situation. Therefore, the correct answer is to assess the client for fluid volume deficit. Fluid volume excess is characterized by decreased urine osmolarity, while hyperkalemia and hypercalcemia are related to electrolyte imbalances and would not directly cause elevated urine osmolarity.

5. Elderly persons with pernicious anemia should be instructed:

• A. to increase their dietary intake of foods high in B12.
• B. that they do not need to return for follow-up for at least a month after initiation of treatment.
• C. that oral B12 is safer and less expensive than parenteral replacement.
• D. that diarrhea can be a transient side effect of B12 injections.

Correct answer: D

Rationale: Elderly persons with pernicious anemia, a condition characterized by vitamin B12 deficiency due to lack of intrinsic factor, should be informed about the potential side effects of B12 injections. Diarrhea is a known transient side effect of B12 injections, along with pain and burning at the injection site, and peripheral vascular thrombosis. Increasing dietary intake of B12-rich foods would not be sufficient due to the malabsorption issue in pernicious anemia. Follow-up is essential in managing pernicious anemia, so instructing patients they do not need to return for follow-up is incorrect. While oral B12 may be a suitable option for some cases, it is not the preferred choice for pernicious anemia where malabsorption is the primary issue.
