Correct Answer: D

Rationale: The correct answer is D. Deep injection helps to prevent tissue irritation caused by iron, which can be damaging to tissues. Option A is incorrect because deep injection does not primarily aim to enhance absorption, but rather to prevent tissue irritation. Option B is incorrect as the route of administration does not determine whether the entire dose is given. Option C is incorrect because the even distribution of the drug is not the main purpose of deep injection in this context.

Correct Answer: B

Rationale: The correct answer is B: Potassium. Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium while eliminating sodium. This is beneficial for patients with cirrhosis and ascites as they are at risk of low potassium levels. Choice A, Sodium, is incorrect as Spironolactone does not spare the elimination of sodium but rather helps eliminate it. Choice C, Phosphate, is incorrect as Spironolactone does not directly affect phosphate levels. Choice D, Albumin, is incorrect as Spironolactone does not spare the elimination of albumin.

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.

Correct Answer: A

Rationale: Instructing the client to avoid caffeine for 8 hours before the EEG is essential. This intervention helps ensure accurate test results by preventing stimulation of the nervous system, which could interfere with the interpretation of the brain's electrical activity. Explaining the procedure and obtaining consent are important steps but do not directly impact the test results. Administering anticonvulsant medication as ordered is a medical intervention and not a preparation step for the test. Instructing the client to wash their hair the morning of the test is not necessary for EEG preparation.

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.
