Correct Answer: B

Rationale: The correct action the nurse should include in the plan of care for a client with chronic renal failure is to restrict protein intake to the RDA. This is important because limiting protein helps reduce the buildup of waste products that the kidneys are unable to efficiently excrete. Encouraging increased fluid intake (choice A) may further burden the kidneys, increasing the risk of fluid overload. Increasing dietary potassium (choice C) is not recommended in chronic renal failure as impaired kidneys have difficulty regulating potassium levels. Encouraging foods high in sodium (choice D) is also not appropriate as excessive sodium intake can lead to fluid retention and hypertension, which are detrimental in renal failure.

Correct Answer: D

Rationale: The correct answer is D. There is no need to limit fish intake with furosemide, indicating a misunderstanding of dietary restrictions. Furosemide is a diuretic that helps the body get rid of excess water and salt. Choices A, B, and C are all appropriate actions for a client taking furosemide. Taking morning pills with food or milk can help reduce stomach upset, weighing oneself daily helps monitor fluid retention, and notifying the nurse about muscle cramps can be important due to potential electrolyte imbalances.

Correct Answer: C

Rationale: The correct instruction for a client prescribed with doxazosin is to rise slowly when sitting up. Doxazosin can cause orthostatic hypotension, leading to dizziness upon sudden position changes. Instructing the client to rise slowly helps prevent this side effect. Choices A, B, and D are incorrect because they are not directly related to the potential side effects or administration of doxazosin.

Correct Answer: C

Rationale: The correct answer is C: 'Rise slowly when sitting up.' Doxazosin can cause orthostatic hypotension, a sudden drop in blood pressure when standing up, leading to dizziness or fainting. Instructing the client to rise slowly helps prevent this adverse effect. Choices A, B, and D are incorrect. A decrease in caloric intake to reduce weight gain, an increase in dietary fiber to prevent constipation, and taking the medication each morning are not specific instructions related to managing the side effects of doxazosin.

Correct Answer: D

Rationale: Chlorine bleach is the most appropriate agent for disinfecting surfaces contaminated with blood. It is effective in killing a wide range of pathogens, including viruses. Hydrogen peroxide (Choice A) is not as effective as chlorine bleach for bloodborne pathogen disinfection. Chlorhexidine (Choice B) and isopropyl alcohol (Choice C) are more commonly used for skin antisepsis rather than surface disinfection, making them less suitable options in this scenario.
