A community health nurse is teaching a group of clients about first aid for wounds. Which client statement indicates understanding?

Correct Answer: B

Rationale: The correct answer is B. Applying clean dressings over blood-saturated ones and holding pressure helps to control bleeding and prevent tissue disruption. Removing blood-saturated dressings can cause further damage by disrupting the forming clot. Elevating the wound above heart level is beneficial to reduce swelling, but it is not the best immediate action for a blood-saturated dressing. Leaving the wound open to air can increase the risk of infection and slow down the healing process.

Correct Answer: B

Rationale: The correct answer is B. Reducing fluid intake before bedtime helps prevent interruptions in sleep due to bathroom visits, which is crucial for individuals with insomnia. Taking naps throughout the day (choice A) may disrupt nighttime sleep. Drinking coffee (choice C) is counterproductive as it contains caffeine, which can interfere with falling asleep. Increasing screen time before bed (choice D) can negatively impact sleep quality due to the stimulating effects of screens.

Correct Answer: A

Rationale: The correct answer is A: 90-degree angle. The ventrogluteal site is preferred for intramuscular injections because it is away from major nerves and blood vessels. Administering the injection at a 90-degree angle ensures that the medication reaches deep into the muscle tissue, allowing for proper absorption of the drug. Choice B, 60-degree angle, is incorrect as it is not the recommended angle for the ventrogluteal site. Choice C, 75-degree angle, and Choice D, 45-degree angle, are also incorrect as they are not the appropriate angles for administering an intramuscular injection using the ventrogluteal site.

Correct Answer: A

Rationale: Before administering blood products, assessing the patient's temperature is crucial. This action provides baseline data to detect any febrile reactions during or after the transfusion. Fever may indicate a transfusion reaction, so continuous monitoring of vital signs is essential throughout the procedure. Documenting the patient's response (choice B) is important but comes after assessing the temperature. Priming IV tubing with 0.45% sodium chloride (choice C) is not directly related to the initial action required before administering blood products. Administering epinephrine (choice D) is not indicated unless there is a severe allergic reaction, which is not the standard initial step before blood product administration.

Correct Answer: A

Rationale: The correct answer is A. Doxazosin can cause first-dose orthostatic hypotension, which may lead to dizziness or fainting when the client stands up too quickly. The nurse should advise the client to change positions slowly and lie down if dizziness occurs to prevent falls and other injuries. Choice B is incorrect because while the client can continue normal activities, caution should be taken with position changes. Choice C is incorrect as doxazosin does not interact with dairy products. Choice D is incorrect as there is no need to avoid green leafy vegetables specifically while taking doxazosin.
