A nurse is caring for a client who has dehydration. The client has a peripheral IV and has a prescription for an infusion of 0.9% sodium chloride 1,000 mL with 40 mEq potassium chloride to infuse over 1 hr. Which of the following actions should the nurse take first?

Correct Answer: D

Rationale: The priority action is to verify the prescription with the provider. Verifying the prescription ensures patient safety by preventing fluid volume overload and dysrhythmias, which can result from infusing potassium too rapidly. Teaching the client about IV extravasation, evaluating IV patency, and consulting with the pharmacist are important but should come after verifying the prescription to ensure the ordered treatment is appropriate and safe for the client's condition.

Correct Answer: D

Rationale: Clients who have seizures are at risk for injury and aspiration. Therefore, the nurse should instruct the family to position the client on their side during a seizure to maintain a clear airway. Placing a padded tongue depressor near the bedside (Choice A) is not recommended, as it can lead to oral injury during a seizure. Placing a pillow under the client's head (Choice B) can obstruct the airway and increase the risk of aspiration. Administering diazepam orally (Choice C) is not typically done by family members during a seizure; this is usually prescribed by healthcare providers for specific situations.

Correct Answer: D

Rationale: The correct answer is D. During an electromyography (EMG) procedure, small needle electrodes are inserted into the muscles to identify muscle weakness and evaluate local nerve responses. This information is crucial for the client to know beforehand. Choice A is incorrect because radioisotopes are not used in EMG procedures. Choice B is incorrect because flushing is not a common occurrence during EMG. Choice C is incorrect because claustrophobia is more relevant to MRI or CT scans, not EMG procedures.

Correct Answer: C

Rationale: The client presents with bradycardia, diaphoresis, and chest pain, indicating reduced cardiac output. Atropine is the appropriate choice as it increases heart rate by blocking the parasympathetic nervous system. Lidocaine is used for ventricular arrhythmias, Adenosine for supraventricular tachycardia, and Verapamil for controlling heart rate in atrial fibrillation or atrial flutter. These medications are not suitable for the client's current presentation.

Correct Answer: D

Rationale: The correct answer is D. Limiting activities that require bending at the waist can help prevent episodes of reflux in clients with GERD. Choices A, B, and C are incorrect. Taking medicine with orange juice may not be appropriate as citrus juices can aggravate GERD. Having a bedtime snack can exacerbate heartburn by increasing stomach acid production, and lying down after meals can worsen symptoms of GERD by allowing stomach acid to flow back into the esophagus.

Correct Answer: A

Rationale: The correct instruction the nurse should provide is that the medication can cause the client's urine to turn a dark color, which is a harmless effect of carbidopa/levodopa. This is due to the metabolites of levodopa. Immediate relief is not expected after taking the medication because it may take weeks to months to achieve the full therapeutic effect. Taking the medication with a high-protein food is not recommended as protein can interfere with the absorption of levodopa. Skipping a dose of the medication if the client experiences dizziness is incorrect as dizziness may be a side effect of the medication, and doses should not be skipped without consulting a healthcare provider.

Correct Answer: B

Rationale: The correct answer is B because shortness of breath is an indication of transplant rejection, along with other manifestations like fatigue, edema, bradycardia, and hypotension. Choice A is incorrect because immunosuppressant medications are usually taken for life to prevent rejection. Choice C is incorrect as the surgical site may take longer to heal fully. Choice D is incorrect as the initiation of exercise post-heart transplant should be gradual and individualized based on the client's condition.

Correct Answer: C

Rationale: The correct answer is C: Hypertension. Prednisone, a corticosteroid, can lead to hypertension as an adverse effect. Prednisone can cause sodium and water retention, leading to increased blood pressure. Options A, B, and D are incorrect. Weight loss is not typically associated with prednisone use; instead, weight gain is more common. Hypoglycemia is not a common adverse effect of prednisone; in fact, it can elevate blood sugar levels. Hyperkalemia is also not a typical adverse effect of prednisone; instead, it can cause hypokalemia, or low potassium levels.

Correct Answer: B

Rationale: When using the ABC approach to client care, the nurse should identify that the priority intervention is administering oxygen. In this scenario, the client's oxygen saturation is only 91%, which is below the normal range of 95% and above. Oxygen is essential for adequate tissue perfusion and oxygenation of vital organs. Administering oxygen takes precedence over other interventions to ensure the client's physiological needs are met first. Choice A can be addressed after ensuring adequate oxygenation. Choice C is important for preventing postoperative complications but is not as urgent as addressing oxygen saturation. Choice D is a common postoperative intervention, but in this case, ensuring adequate oxygenation is the priority over IV fluid administration.
