which client is at risk for hypomagnesemia

NCLEX-PN

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 nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?

A. Hypocalcemia.
B. Hyponatremia.
C. Hyperkalemia.
D. Hypophosphatemia.

Correct answer: A.

Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.

3. Which type of hepatitis is transmitted via the fecal-oral route?

A. Hepatitis A
B. Hepatitis B
C. Hepatitis C
D. Hepatitis D

Correct answer: A

Rationale: Hepatitis A is the correct answer because it is transmitted via the fecal-oral route, often through contaminated food or water. Hepatitis B is transmitted through exposure to infectious blood, semen, and other body fluids, not through the fecal-oral route. Hepatitis C is transmitted through blood-to-blood contact, not via the fecal-oral route. Hepatitis D occurs only in individuals infected with Hepatitis B. Therefore, the correct choice for the type of hepatitis transmitted via the fecal-oral route is Hepatitis A.

4. A 70-year-old male who is recovering from a stroke exhibits signs of unilateral neglect. Which behavior is suggestive of unilateral neglect?

A. The client is observed shaving only one side of his face.
B. The client is unable to distinguish between two tactile stimuli presented simultaneously.
C. The client is unable to complete a range of vision without turning his head side to side.
D. The client is unable to carry out cognitive and motor activity at the same time.

Correct answer: A

Rationale: Unilateral neglect is a condition where a person ignores one side of their body. In this case, the behavior of shaving only one side of the face indicates neglect of the other side. This behavior is suggestive of unilateral neglect as the individual is failing to attend to one side of their body. Choices B, C, and D are not associated with unilateral neglect. Choice B refers to tactile agnosia, a condition where a person cannot recognize objects by touch, not related to ignoring one side of the body. Choice C describes a visual field cut, which is a different visual deficit. Choice D relates to dual-task interference, not specific to ignoring one side of the body.

5. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

A. It protects the bacteria from antibiotic and immunologic destruction.
B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
C. It competes with the antibiotic for binding sites on the microbe.
D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.
