which client is at risk for hypomagnesemia

Kaplan NCLEX Question of The Day

1. 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.

2. The client is preparing to learn about the effects of isoniazid (INH). Which information is essential for the client to understand?

A. Isoniazid should be taken with meals to reduce gastrointestinal upset.
B. Prolonged use of isoniazid may result in dark, concentrated urine.
C. Taking aluminum hydroxide (Maalox) with isoniazid can enhance the drug's effects.
D. Consuming alcohol daily can increase the risk of drug-induced hepatitis.

Correct answer: D

Rationale: It is crucial for the client to understand that consuming alcohol while on isoniazid can increase the risk of drug-induced hepatitis. Hepatic damage can lead to dark, concentrated urine. To minimize gastrointestinal upset, it is recommended to take isoniazid with meals rather than on an empty stomach. Additionally, the client should avoid taking aluminum-containing antacids like aluminum hydroxide with isoniazid, as it can reduce the drug's effectiveness. Choice A is incorrect because isoniazid should not be taken on an empty stomach to help reduce GI upset. Choice B is incorrect, as prolonged use of isoniazid does not typically cause dark, concentrated urine. Choice C is incorrect as taking aluminum hydroxide with isoniazid does not enhance the drug's effects; in fact, it may decrease its effectiveness.

3. Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?

A. Alpha tocopherol (vitamin E)
B. Ascorbic acid (vitamin C)
C. Calcitriol (vitamin D)
D. Pyridoxine (vitamin B6)

Correct answer: D

Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.

4. 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.

5. An RN on your unit has had an argument with the family of a client regarding the way in which the RN has changed the client's dressing. The family is adamant that the dressing change was performed incorrectly. The RN insists that sterile technique was observed. As an RN manager, what is the best response?

A. Meet with the family member and the RN to discuss the disagreement regarding the dressing change.
B. Talk to the family member and assure them that the nurse followed the hospital procedure.
C. Discuss the dressing change procedure with the RN and compare it to a current textbook.
D. Change the RN's assignment the next day to another client.

Correct answer: A

Rationale: When conflict occurs, it is best to meet with both parties together to discuss the problem. This approach allows each party to hear what the other is saying and prevents the RN manager from being caught in the middle. By facilitating a discussion between the family member and the RN, they can work together to find a resolution or the manager can mediate. This promotes open communication, understanding, and collaboration. Option A is the correct choice because it emphasizes addressing the conflict directly and seeking a mutual understanding. Option B is incorrect because just assuring the family member may not address the underlying issues. Option C is incorrect as it does not involve the family member in the resolution process. Option D is inappropriate as it doesn't address the conflict but rather avoids it by changing the RN's assignment.
