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: Urinary incontinence is a risk factor for developing pressure injuries as it can lead to skin breakdown due to constant exposure to moisture and irritation. Increased fluid intake is important for hydration and overall health but is not directly linked to pressure injuries. Poor nutrition can impair wound healing but is not a direct risk factor for pressure injuries. Immobility can contribute to the development of pressure injuries but is not as directly related as urinary incontinence.

Correct Answer: B

Rationale: The correct answer is to 'Use sequential compression devices.' Sequential compression devices help prevent DVT by promoting venous return, reducing stasis in the veins, and preventing blood clot formation. Resting in bed for long periods (Choice A) can actually increase the risk of DVT due to decreased mobility. Avoiding leg exercises (Choice C) is also not recommended as mobilization and exercises can help prevent blood clots. Keeping legs crossed (Choice D) can impede blood flow and is not advisable in reducing the risk of DVT.

Correct Answer: C

Rationale: The correct answer is C: 'Use cotton fabrics when oxygen is in use.' When a client is on oxygen therapy, it is essential to use cotton fabrics to reduce the risk of static electricity, which can ignite in the presence of oxygen. Choices A, B, and D are incorrect. Removing the oxygen tubing during meals is not necessary as long as proper precautions are taken to avoid tripping hazards. Synthetic fabrics should be avoided while using oxygen therapy to prevent static electricity buildup. Increasing oxygen flow during physical activity should be done according to the healthcare provider's instructions, not indiscriminately.

Correct Answer: B

Rationale: Frequent urge suppression can lead to constipation, especially postoperatively. Suppressing the urge to defecate can disrupt normal bowel movements and result in constipation. Increased physical activity, increased fiber intake, and adequate fluid intake are measures that typically help prevent constipation by promoting bowel regularity and preventing stool hardening. Therefore, choices A, C, and D are not behaviors that increase the client's risk for constipation.
