Correct Answer: B

Rationale: The correct answer is 'Increased hematocrit.' In fluid volume deficit (FVD), there is a decrease in the amount of fluid in the blood vessels, leading to hemoconcentration. This results in an increase in hematocrit levels. Choices A, C, and D are incorrect because a decrease in hematocrit, decrease in white blood cell count, and an increase in red blood cell count are not typically seen in fluid volume deficit.

Correct Answer: B

Rationale: The correct answer is B: 'Use a special mattress for the client.' Using a special mattress reduces pressure on bony prominences and helps prevent pressure injuries. Repositioning the client every 4 hours (choice A) is important but using a special mattress is more effective. Keeping the client on bedrest (choice C) can increase the risk of pressure injuries due to prolonged immobility. Encouraging the client to remain in one position (choice D) is incorrect as it can lead to pressure injuries by exerting pressure on the same areas for an extended period.

Correct Answer: B

Rationale: The ventrogluteal site is the preferred site for intramuscular injections to avoid injury to nerves or blood vessels. The deltoid site is commonly used for vaccines but has a higher risk of hitting the radial nerve. The rectus femoris site is not typically recommended for intramuscular injections. The dorsogluteal site is contraindicated due to the proximity to the sciatic nerve and major blood vessels.

Correct Answer: B

Rationale: The correct answer is B. Wearing slippers or shoes when out of bed is crucial for clients with diabetes as it helps prevent injuries to the feet, reducing the risk of infection. Choices A, C, and D are incorrect. Soaking feet in hot water daily can lead to dryness and skin damage, applying lotion between toes can create a moist environment promoting fungal growth, and cutting nails in a rounded shape can increase the risk of ingrown nails.

Correct Answer: B

Rationale: The ventrogluteal muscle is the preferred site for intramuscular injections to avoid injury. Choosing the ventrogluteal site reduces the risk of injury to major nerves and blood vessels, unlike the deltoid, rectus femoris, or dorsogluteal sites. The deltoid muscle is commonly used for vaccines but has a higher risk of injury due to its proximity to the radial nerve. The rectus femoris muscle is not recommended for intramuscular injections due to its location and the risk of injury. The dorsogluteal site is also not recommended as it poses a risk of injury to the sciatic nerve and superior gluteal artery.
