Correct Answer: C

Rationale: Monitoring vital signs is crucial after a renal biopsy to promptly detect any signs of bleeding or complications. Ambulating the client 4 hours after the procedure may increase the risk of bleeding, so it is not appropriate. Maintaining the client on NPO status for 24 hours is not necessary unless specifically ordered by the healthcare provider. Changing the dressing every 8 hours is not typically indicated unless there is a specific concern or order to do so.

Correct Answer: A

Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.

Correct Answer: A

Rationale: Chocolate pudding is the best snack food choice for a client with myasthenia gravis at risk for altered nutritional status due to its nutrient density and soft texture, which can be easier for clients with swallowing difficulties to consume. Graham crackers, sugar-free gelatin, and apple slices may not provide the same level of nutrient density or ease of consumption for these clients. Graham crackers and apple slices may also pose challenges for clients with swallowing difficulties, while sugar-free gelatin, although a good option for some clients, may not offer the same level of nutrition as chocolate pudding.

Correct Answer: B

Rationale: In the scenario described, the client is experiencing symptoms of an anaphylactic reaction, a severe allergic response. The priority action in an anaphylactic reaction is to administer epinephrine. Epinephrine helps counteract the severe allergic response, improves breathing difficulties, and maintains airway and circulation. Administering epinephrine takes precedence to stabilize the client's condition. Options A, C, and D may be necessary in the management of anaphylaxis, but the immediate priority is to administer epinephrine to address the life-threatening symptoms.

Correct Answer: B

Rationale: The ventrogluteal site is the most appropriate and safest site for administering an intramuscular injection to an adult client. It is preferred due to its thick muscle mass and fewer major blood vessels and nerves in the area, reducing the risk of injury or complications. The deltoid muscle is commonly used for vaccines and small-volume injections but may not be suitable for larger volumes. The dorsogluteal site has fallen out of favor due to the risk of injury to the sciatic nerve and other underlying structures. The rectus femoris site is not typically used for intramuscular injections in adults.
