A nurse is caring for four clients. The nurse should observe which of the following clients for a risk of vitamin B6 deficiency?

A. A client who has cystic fibrosis

B. A client who has chronic alcohol use disorder

C. A client who takes phenytoin for a seizure disorder

D. A client who is prescribed rifampin for tuberculosis

Correct Answer: B
Rationale: Chronic alcohol use disorder can lead to vitamin B6 deficiency due to impaired absorption and increased excretion of the vitamin. While clients with cystic fibrosis may be at risk for fat-soluble vitamin deficiencies, such as vitamins A, D, E, and K, they are not specifically at high risk for vitamin B6 deficiency. Clients taking phenytoin are at risk for folate deficiency, not vitamin B6. Clients prescribed rifampin for tuberculosis are at risk for vitamin D deficiency, not vitamin B6.

A client has been diagnosed with hyperthyroidism. Which of these nursing diagnoses should receive the highest priority?

• A. Risk for injury related to exophthalmos
• B. Impaired social interaction related to emotional lability
• C. Imbalanced nutrition: Less than body requirements related to hypermetabolism
• D. Activity intolerance related to fatigue

Correct Answer: D
Rationale: The correct answer is 'D: Activity intolerance related to fatigue.' This nursing diagnosis should receive the highest priority for a client with hyperthyroidism. Hyperthyroidism often leads to symptoms such as fatigue, weakness, and muscle discomfort, which can significantly impact the client's ability to perform daily activities. Addressing activity intolerance is crucial to prevent exacerbation of symptoms and promote the client's overall well-being. Choices A, B, and C are important nursing diagnoses as well, but in the context of hyperthyroidism, addressing activity intolerance takes precedence over the risk for injury related to exophthalmos, impaired social interaction related to emotional lability, and imbalanced nutrition due to hypermetabolism.

A client with hypertension taking a potassium-wasting diuretic is being educated about nutrition by a nurse. Which of the following dietary instructions should the nurse include in the teaching?

• A. Increase consumption of tuna and salmon.
• B. Limit intake of dried fruits.
• C. Avoid cow's milk.
• D. Consume organs and bananas

Correct Answer: D
Rationale: The correct answer is D: 'Consume organs and bananas.' When a client is taking a potassium-wasting diuretic, they are at risk of potassium loss. Consuming foods high in potassium, such as organs and bananas, can help counteract this loss. Choice A is incorrect because tuna and salmon are not particularly high in potassium. Choice B is incorrect because dried fruits are good sources of potassium. Choice C is incorrect as cow's milk is also a good source of potassium, which could be beneficial for a client taking a potassium-wasting diuretic.

When a client is receiving external beam radiation to the mediastinum for treatment of bronchial cancer, which of the following should take priority in planning care?

• A. Esophagitis
• B. Leukopenia
• C. Fatigue
• D. Skin irritation

Correct Answer: B
Rationale: Leukopenia should take priority in planning care for a client receiving external beam radiation to the mediastinum for bronchial cancer because it is a serious side effect that increases the risk of infection. Monitoring leukopenia is crucial to prevent complications. Esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, but leukopenia poses a higher risk of life-threatening infections, requiring immediate attention.

The nurse is about to assess a 6-month-old child with nonorganic failure-to-thrive (NOFTT). Upon entering the room, the nurse would expect the baby to be

• A. Irritable and 'colicky' with no attempts to pull to standing
• B. Alert, laughing, and playing with a rattle, sitting with support
• C. Skin color dusky with poor skin turgor over the abdomen
• D. Pale, thin arms and legs, uninterested in surroundings

Correct Answer: D
Rationale: A baby with nonorganic failure-to-thrive often appears pale, thin, and uninterested in their surroundings. Choice A is incorrect as 'irritable and colicky with no attempts to pull to standing' is more indicative of other conditions like colic. Choice B is incorrect as a baby with nonorganic failure-to-thrive is unlikely to be alert, laughing, and playing, as they would typically present with signs of failure to thrive. Choice C is incorrect as dusky skin color and poor skin turgor are not typical findings in a baby with nonorganic failure-to-thrive.
