Correct Answer: A

Rationale: A serum albumin level of 3 g/dL is indicative of poor nutrition, which is commonly associated with pressure ulcers. This finding suggests that the client may be at risk for developing or already has a pressure ulcer due to malnutrition. High-density lipoprotein (HDL) level of 90 mg/dL (Choice B) is not directly related to pressure ulcers. The Norton scale (Choice C) is used to assess a client's risk of developing pressure ulcers, not as a finding in a client with an existing pressure ulcer. The Braden scale (Choice D) is also a tool used to assess the risk of developing pressure ulcers, not a finding in a client with an existing pressure ulcer.

Correct Answer: D

Rationale: The correct answer is D: Consumption of contaminated food. Hepatitis A is primarily transmitted through the ingestion of contaminated food or water. Airborne droplets and sexual contact are not common modes of transmission for hepatitis A. While contact with contaminated surfaces can play a role in the spread of some infections, hepatitis A is not typically transmitted through this route.

Correct Answer: D

Rationale: When a client refuses medication, the nurse should inform the client of the possible consequences of refusal. This action helps the client understand the risks associated with not taking the medication. Asking the client to discuss their feelings (choice A) is important but should follow after informing them of the consequences. Explaining the importance of the medications (choice B) might not address the immediate concern of the client. Documenting the refusal and withholding the medication (choice C) should be done after informing the client of the consequences and attempting to address their concerns.

Correct Answer: A

Rationale: The correct answer is A: Immobility and oral contraceptive use. Immobility and oral contraceptive use are significant risk factors for deep vein thrombosis (DVT). Immobility leads to blood stasis, increasing the risk of clot formation, while oral contraceptive use can promote hypercoagulability. Prevention strategies for DVT include promoting mobility to enhance blood circulation and using anticoagulants to prevent clot formation. Choices B, C, and D are incorrect. While pregnancy and smoking can increase the risk of DVT, they are not the specific factors mentioned in the question. Similarly, obesity and varicose veins, as well as hypertension and high cholesterol, are not the primary risk factors associated with DVT.

Correct Answer: C

Rationale: The correct answer is to administer naloxone (Narcan). The client's vital signs indicate opioid-induced respiratory depression, which is a potential side effect of morphine. Naloxone is used to reverse the effects of opioids, particularly to restore normal respiratory function. Administering oxygen alone (Choice B) may not address the underlying cause of respiratory depression. Allowing the client to sleep undisturbed (Choice A) is inappropriate when signs of respiratory depression are present. Epinephrine (Choice D) is not indicated in this situation and is not used to reverse opioid effects.
