Which electrolyte imbalance is commonly seen in patients taking furosemide?

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as the priority nursing action for a patient experiencing an acute asthma attack. Bronchodilators help open the airways and improve airflow, which is crucial in managing the acute respiratory distress in asthma. Corticosteroids may be used subsequently to reduce inflammation, but in the acute phase, bronchodilators take precedence. Providing supplemental oxygen is important but may not address the underlying bronchoconstriction characteristic of an asthma attack. Starting IV fluids is not a priority in managing an acute asthma attack unless indicated for specific reasons such as dehydration.

Correct Answer: A

Rationale: Administering diuretics is the best method to manage fluid overload in a patient with heart failure. Diuretics help to remove excess fluid from the body by increasing urine output, thus reducing the fluid volume in the bloodstream and tissues. Providing oral fluids (choice B) or increasing fluid intake (choice C) would exacerbate the fluid overload rather than managing it. Chest physiotherapy (choice D) is not indicated for managing fluid overload in heart failure; it is more commonly used for conditions affecting the lungs or airways.

Correct Answer: A

Rationale: The correct initial intervention for a patient with chest pain is to administer aspirin. Aspirin helps reduce the risk of clot formation by inhibiting platelet aggregation, which can be beneficial in case the chest pain is due to a cardiac event. Administering nitroglycerin may follow aspirin administration to help relieve chest pain by dilating blood vessels. Providing pain relief is a general approach and may not address the underlying cause of chest pain. Preparing for surgery would not be the initial intervention for chest pain unless there are specific indications for immediate surgical intervention.

Correct Answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.
