Which electrolyte imbalance is most concerning for a patient on loop diuretics?

Correct Answer: A

Rationale: The correct answer is hypokalemia. Loop diuretics can cause potassium depletion leading to hypokalemia, which is particularly concerning as it can result in cardiac arrhythmias. Hyponatremia (choice B) is not typically associated with loop diuretics. Hyperkalemia (choice C) is less common in patients on loop diuretics. Hypercalcemia (choice D) is not a typical electrolyte imbalance associated with loop diuretics.

Correct Answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

Correct Answer: A

Rationale: The correct answer is to document the time the medication was given. This is essential for understanding the sequence of events surrounding the medication error. While documenting the client's response to the medication (Choice B) is important for assessing any effects, the immediate concern should be to establish a clear timeline by documenting the time of administration. Recording the dose administered (Choice C) is also important, but in the context of understanding the incident, the time factor takes precedence. The reason for the error (Choice D) should be included in the incident report but may not be the first priority when documenting in the client's medical record.

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: B

Rationale: The correct answer is B: 'Place the client in airborne isolation.' Tuberculosis is an airborne disease transmitted through droplet nuclei. Placing the client in airborne isolation helps prevent the spread of the disease to others. Choice A, placing the client in droplet isolation, is incorrect because tuberculosis is not transmitted through large droplets. Choice C, wearing a surgical mask when providing care to the client, is not sufficient as airborne precautions are necessary. Choice D, keeping the client's door closed at all times, does not directly address the prevention of disease transmission in this case.

Correct Answer: A

Rationale: The best position for a patient in respiratory distress is the Semi-Fowler's position. This position promotes lung expansion and eases breathing by allowing the chest to expand more fully. The Trendelenburg position (choice B) where the patient's feet are higher than the head is not recommended in respiratory distress as it may cause increased pressure on the chest and reduced lung expansion. The prone position (choice C) lying on the stomach is also not optimal for respiratory distress as it can further compromise breathing. The supine position (choice D) lying flat on the back is not ideal as it may impair breathing by restricting chest expansion.

Correct Answer: D

Rationale: The correct answer is D. Dark, tarry stools indicate gastrointestinal bleeding, which is a serious side effect of enoxaparin that requires immediate medical attention. Reporting this finding promptly is crucial to prevent further complications. Choices A, B, and C are within normal ranges and are not directly related to the adverse effects of enoxaparin, so they do not take precedence over the urgent concern of gastrointestinal bleeding.

Correct Answer: C

Rationale: The correct instruction the nurse should include is to perform weight-bearing exercises regularly. Weight-bearing exercises help maintain bone density and reduce the risk of fractures in clients with osteoporosis. Increasing intake of calcium-rich foods (Choice A) is also beneficial for bone health. Avoiding weight-bearing exercises (Choice B) is incorrect as these exercises are essential for strengthening bones. Avoiding calcium supplements (Choice D) may not be necessary if the client's dietary intake is inadequate.

Correct Answer: B

Rationale: The best position for a patient experiencing shortness of breath is the Semi-Fowler's position. This position promotes lung expansion and improves oxygenation by allowing the chest to expand more fully. The Supine position (lying flat on the back) may worsen breathing difficulties by reducing lung capacity. The Trendelenburg position (feet elevated higher than the head) is not recommended for patients with shortness of breath as it can increase pressure on the diaphragm and compromise breathing. The Prone position (lying face down) is also not suitable for patients experiencing shortness of breath as it may further restrict breathing.
