Which lab value should be monitored in a patient on digoxin?

Correct Answer: C

Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.

Correct Answer: A

Rationale: When assessing for infection in a patient post-surgery, checking the surgical site is crucial. Changes in the appearance of the surgical site, such as redness, swelling, warmth, or drainage, can indicate an infection. While checking for fever (Choice B) is also important as it can be a sign of infection, it is a more general symptom and may not always be present. Checking for abnormal breath sounds (Choice C) and skin color (Choice D) are not typically direct indicators of infection in a post-surgery patient.

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: Administering oxygen is the best intervention for a patient with a suspected pulmonary embolism because it helps alleviate respiratory distress and improve oxygenation. Oxygen therapy is crucial to ensure adequate oxygen levels in the blood due to the obstruction in the pulmonary circulation caused by the embolism. Administering anticoagulants (choice B) is a treatment for confirmed pulmonary embolism rather than a suspected case. Repositioning the patient (choice C) or administering bronchodilators (choice D) would not directly address the underlying issue of impaired gas exchange and oxygen delivery associated with pulmonary embolism.

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.
