Correct Answer: B

Rationale: The correct answer is to emphasize limiting the intake of potassium and phosphorus for a client with chronic kidney disease. Excessive intake of potassium and phosphorus can lead to complications in kidney disease patients. Choice A is incorrect because increasing protein intake can put additional stress on the kidneys. Choice C is incorrect as excessive fluid intake can worsen kidney function in such clients. Choice D is incorrect as encouraging high-sodium foods can lead to fluid retention and hypertension, which are not beneficial for individuals with chronic kidney disease.

Correct Answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.

Correct Answer: D

Rationale: The correct answer is D because a client with pneumonia and a new onset of confusion needs immediate evaluation for changes in neurological status. This could indicate a decline in respiratory status or potential complications such as hypoxia or sepsis. Option A, a client who is NPO and has dry mucous membranes, may need intervention but does not indicate an acute change in condition. Option B, a client with rotavirus who has been vomiting, requires assessment and intervention but does not pose an immediate threat to life. Option C, a client with a urinary catheter and cloudy urine, may indicate a urinary tract infection but does not require immediate attention compared to the client with new onset confusion and pneumonia.

Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the priority action for the nurse is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and removing the IV can help prevent further complications. Applying a warm compress may provide symptomatic relief but does not address the root cause. Monitoring for infection is important, but immediate action to remove the source of inflammation is crucial. Administering an anti-inflammatory medication is not the first-line intervention for phlebitis; removal of the IV is necessary.

Correct Answer: A

Rationale: The correct intervention for a patient experiencing hypovolemic shock is to administer IV fluids. In hypovolemic shock, there is a significant loss of circulating blood volume leading to inadequate perfusion to tissues. Administering IV fluids is crucial to restore blood volume and improve tissue perfusion. Monitoring blood pressure (choice B) is important but not the primary intervention in hypovolemic shock. Placing the patient in Trendelenburg position (choice C) can worsen outcomes by increasing intracranial pressure and is no longer recommended. Administering oxygen (choice D) is beneficial for many conditions but does not address the underlying issue of inadequate circulating blood volume in hypovolemic shock.
