Correct Answer: B

Rationale: The correct answer is B: Limit phosphorus and potassium intake. In chronic kidney disease, the kidneys are unable to effectively filter these minerals from the blood, leading to their accumulation and potential complications. Restricting phosphorus and potassium intake is crucial in managing the progression of the disease. Choice A is incorrect as increasing potassium-rich foods can worsen the condition. Choice C is also incorrect as excessive protein intake can put more strain on the kidneys. Choice D is not the priority; rather, fluid intake should be monitored based on individual needs and stage of kidney disease.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps improve oxygenation by preventing airway collapse, slowing down the breathing rate, and promoting better gas exchange. Administering oxygen at 2L/min via nasal cannula is not the first-line intervention as it can cause oxygen toxicity in COPD patients. Positioning the client in high Fowler's position may improve ventilation but does not specifically address the breathing technique required for COPD. Encouraging deep breathing and coughing is generally not recommended for clients with COPD as it can lead to air trapping and increased work of breathing.

Correct Answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

Correct Answer: A

Rationale: The correct answer is A: Increased heart rate and fever. These are early signs of sepsis and indicate a systemic infection. It is crucial to identify these signs promptly to initiate appropriate treatment. Choice B is incorrect because low blood pressure and confusion are more indicative of severe sepsis or septic shock rather than early signs. Choice C is incorrect as elevated blood sugar and sweating are not typical early signs of sepsis. Choice D is also incorrect as increased urine output and abdominal pain are not early signs of sepsis.

Correct Answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This action helps stimulate voiding post-catheterization by promoting relaxation and providing sensory input. Assessing for bladder distention after 6 hours (Choice A) is important but not the immediate intervention needed for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not effectively address the issue of post-catheterization voiding difficulty. Restricting the client's intake of oral fluids (Choice C) is not appropriate and can lead to dehydration, which is not helpful in promoting voiding.
