Correct Answer: B

Rationale: The correct answer is B: 'Limit fluid intake to 1-2 liters per day.' For clients with heart failure, fluid restriction is essential to prevent fluid overload. Restricting fluid intake to 1-2 liters per day helps maintain fluid balance and prevents exacerbation of heart failure symptoms. Choices A, C, and D are incorrect because consuming 3 liters, 4 liters, or limiting water intake to 1 liter per day, respectively, can lead to fluid overload in clients with heart failure.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with chest pain because it helps relieve chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Assessing pain level, monitoring vital signs, and providing oxygen therapy are important interventions as well, but administering nitroglycerin takes precedence in addressing the immediate symptom of chest pain and potential cardiac ischemia.

Correct Answer: C

Rationale: The correct answer is C. In a nonstress test, the client is required to press a handheld button whenever fetal movement is felt, which is then recorded on the monitor. This action helps assess the baby's heart rate in response to its movements, providing valuable information about the baby's well-being. Choices A, B, and D are incorrect because the nonstress test does not involve determining the length of the cervix, monitoring blood pressure, or being completed in 5 minutes. These aspects are not part of the nonstress testing procedure and are unrelated to the purpose of the test.

Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy first. When a client with a tracheostomy is experiencing increased secretions and labored breathing, suctioning the tracheostomy is the priority intervention to clear the airway and improve breathing. Administering a bronchodilator (Choice A) may help with breathing but should come after ensuring the airway is clear. Encouraging the client to cough (Choice C) may not be effective in clearing secretions from the tracheostomy. Notifying the provider (Choice D) can be done after ensuring immediate airway clearance.

Correct Answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.
