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 client is at risk for hypomagnesemia?
- A. Client with a history of heart disease
- B. Client taking magnesium-based antacids
- C. Client with a parathyroid disorder
- D. Client admitted with alcohol abuse
Correct answer: D
Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.
3. Which deficiency in the mother has been primarily associated with neural tube defects in the fetus?
- A. Iron
- B. Folic acid
- C. Vitamin B12
- D. Vitamin E
Correct answer: B
Rationale: Folic acid deficiency in the mother has been primarily associated with neural tube defects in the fetus. Folic acid is crucial for the development of the neural tube in the early stages of pregnancy. Its deficiency can lead to neural tube defects, such as spina bifida or anencephaly. Iron deficiency is not directly related to neural tube defects but can cause other complications in pregnancy. Vitamin B12 is important for neurological function but is not the primary cause of neural tube defects. Vitamin E deficiency is not associated with neural tube defects in the fetus.
4. While making rounds at 3 am, the nurse discovers a small fire in a client's room. What should the nurse do first?
- A. Remove the client from the room immediately.
- B. Leave the client's room to obtain a fire extinguisher.
- C. Instruct a nurse tech to pull the fire alarm.
- D. Evacuate all clients from the unit.
Correct answer: A
Rationale: During a fire emergency, the priority is the safety of the individual in the room where the fire is located. Removing the client from the room immediately is the first step in the RACE acronym for fire safety: Rescue/Remove, Alarm, Contain, and Extinguish. This action ensures the client's safety before addressing the fire itself. Choice B is incorrect as leaving the client's room to obtain a fire extinguisher can delay the immediate removal of the client from the danger. Choice C is incorrect as pulling the fire alarm should be done after ensuring the client's safety. Choice D is incorrect as evacuating all clients from the unit should come after ensuring the safety of the individual in immediate danger.
5. A client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:
- A. within normal limits, so a weight-reduction diet is unnecessary
- B. lower than normal, so education about nutrient-dense foods is needed
- C. indicating obesity because the BMI is 35
- D. indicating overweight status because the BMI is 27
Correct answer: C
Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. It is calculated by utilizing a chart or nomogram that plots height and weight. This client's BMI is 35, indicating obesity. Choices A, B, and D are incorrect because the client's BMI is above 30, which falls under the obesity category. Therefore, a weight-reduction diet and increased physical activity are necessary to address the client's weight status and promote overall health.
