Correct Answer: A

Rationale: The correct answer is A because taking the pulse before administering digoxin is crucial as the medication can cause bradycardia. Monitoring the pulse helps in identifying any signs of bradycardia, a common side effect of digoxin. Options B, C, and D are incorrect. Taking digoxin with an antacid may interfere with its absorption. Doubling the dose if a dose is missed can lead to overdose and adverse effects. Avoiding bananas is not specifically related to digoxin therapy.

Correct Answer: D

Rationale: Lubricating the catheter tip before insertion is crucial for female urinary catheterization. This step helps reduce discomfort for the patient and facilitates smooth catheter insertion into the urethra. Using sterile technique maintains asepsis during the procedure, inserting the catheter 2-3 inches ensures proper placement, and inflating the balloon after insertion secures the catheter in place without causing trauma. Proper technique is fundamental for patient comfort, preventing infection, and ensuring the success of the catheterization procedure.

Correct Answer: A

Rationale: Placing a pillow between the client's legs is crucial post hip arthroplasty surgery to prevent hip dislocation. This intervention helps maintain proper alignment and prevents legs from crossing midline, reducing the risk of hip prosthesis dislocation. Elevating the head of the bed to 45 degrees, positioning the client on the operative side, or keeping the client's legs adducted are not recommended postoperative interventions for a total hip arthroplasty, as they can increase the risk of complications and compromise the surgical site.

Correct Answer: C

Rationale: Aspirating before injecting the medication is a crucial step in IM injections to check for blood return, ensuring that the needle is not in a blood vessel. This technique helps prevent accidental intravascular injection of the medication, reducing the risk of complications such as inadvertent intravenous administration of the substance.

Correct Answer: C

Rationale: The primary benefit of using electronic health records (EHRs) in healthcare is that they improve the accuracy and completeness of patient information. By utilizing EHRs, healthcare providers have access to more reliable and up-to-date patient data, which leads to better patient care outcomes. This improved accuracy enables healthcare professionals to make better-informed decisions and provide more effective treatments, ultimately enhancing patient safety and quality of care.
