Correct Answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

Correct Answer: C

Rationale: Comparing the client's wristband with the medication administration record is a crucial step in ensuring medication safety. The wristband typically contains unique identifiers such as the client's name, date of birth, and medical record number, which should be cross-checked with the medication administration record to confirm the correct patient. Asking the client to state their name (Choice A) or date of birth (Choice B) may not be as reliable as the information can be misunderstood or miscommunicated. Asking for the room number (Choice D) is not a reliable client identifier for medication administration and does not confirm the patient's identity accurately.

Correct Answer: A

Rationale: To assess skin turgor, the nurse should grasp a skin fold on the chest under the clavicle, release it, and note whether it springs back. This method is preferred for older adults and in cases of significant fluid imbalance. Option B is incorrect as assessing skin turgor on the back of the hand is not the standard assessment site for skin turgor. Option C is incorrect as the abdomen is not the typical area for assessing skin turgor; the chest under the clavicle is a more accurate site. Option D is incorrect as pressing on the forearm is not the appropriate site for evaluating skin turgor; the chest under the clavicle is the recommended location for this assessment.

Correct Answer: B

Rationale: For subcutaneous injections like heparin, a 25-27 gauge needle is recommended, making choice A incorrect. The abdomen is a commonly used site for heparin injection due to its consistent absorption and convenience, making choice B the correct answer. The Z-track technique is not necessary for subcutaneous injections, making choice C unnecessary. Observing for bleb formation is not a standard practice for confirming proper placement of subcutaneous heparin, making choice D incorrect. Therefore, the correct action is to select a site on the client's abdomen for the injection.

Correct Answer: A

Rationale: Explaining the procedure to the client is the initial and most important step that the healthcare professional should take before inserting an NG tube. By explaining the procedure, the healthcare professional ensures the client's understanding, obtains informed consent, and fosters cooperation. Measuring the length of the NG tube, lubricating the tube, and positioning the client in a high Fowler's position are essential steps in the NG tube insertion process but should come after the client has been informed and consented to the procedure.
