Correct Answer: B

Rationale: Coughing up foul-tasting, brown, thick sputum suggests a possible abscess or secondary infection, requiring attention. Choice A may indicate pleurisy, but the focus should be on the sputum. Choice C may be non-specific and could be related to the infection or fever. Choice D is non-specific and may be expected during an infection.

Correct Answer: B

Rationale: In cases of preeclampsia with increasing blood pressure, the priority action for the nurse is to have the client turn to the left side. This position helps improve blood flow to the placenta and fetus, reducing the risk of complications. Checking the protein level in urine (Choice A) is important for assessing preeclampsia but not the immediate priority when blood pressure is increasing. Taking the temperature (Choice C) is not directly related to addressing increased blood pressure in preeclampsia. Monitoring urine output (Choice D) is essential but not the first action to take when blood pressure is rising.

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.

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: C

Rationale: The correct answer is to participate in compressions or breathing. This is essential to ensure continuous and effective CPR. Relieving the nurse performing CPR (Choice A) is not recommended as it can interrupt the life-saving procedure. Going to get the code cart (Choice B) may be necessary in certain situations but should not take precedence over providing immediate assistance in CPR. Validating the client's advanced directive (Choice D) is not the primary role in this scenario where urgent action is needed to support the client's circulation and breathing.
