Nursing Elites

1. The home health nurse provides teaching about insulin self-injection to a client who was recently diagnosed with diabetes mellitus. When the client begins to perform a return demonstration of an insulin injection into the abdomen, which instruction should the nurse provide?

• A. Select a different injection site
• B. Continue with the insulin injection
• C. Keep the skin flat rather than bunched
• D. Lie down flat for better skin exposure

Correct answer: B

Rationale: Choosing to continue with the insulin injection is the correct instruction in this scenario because it allows the client to demonstrate proper technique and reinforces their learning. Selecting a different injection site (choice A) is not necessary if the client is injecting into the abdomen as it is a suitable site. Keeping the skin flat rather than bunched (choice C) is a good practice but is not the priority in this situation where the client is demonstrating the injection technique. Lying down flat for better skin exposure (choice D) is not required and may not be practical for the client during routine self-injections.

2. A female patient will receive doxycycline to treat a sexually transmitted infection (STI). What information will the nurse include when teaching this patient about this medication?

• A. Nausea and vomiting are uncommon adverse effects.
• B. The drug may cause possible teratogenic effects.
• C. Increase intake of dairy products with each dose of this medication.
• D. Use a backup method of contraception if taking oral contraceptives.

Correct answer: D

Rationale: The correct answer is D. The desired action of oral contraceptives can be reduced when taken with tetracyclines like doxycycline. Therefore, patients on oral contraceptives should be advised to use a backup contraception method while taking doxycycline. Choice A is incorrect because nausea and vomiting are common adverse effects of doxycycline. Choice B is incorrect because doxycycline is not known for causing teratogenic effects. Choice C is incorrect because dairy products can interfere with the absorption of doxycycline, so they should be avoided when taking this medication.

3. Healthcare workers must protect themselves against becoming infected with HIV. The Center for Disease Control has issued guidelines for healthcare workers in relation to protection from HIV. These guidelines include which recommendation?

• A. Place HIV-positive clients in strict isolation and limit visitors.
• B. Wear gloves when coming in contact with the blood or body fluids of any client.
• C. Conduct mandatory HIV testing of those who work with clients with AIDS.
• D. Freeze HIV blood specimens at -70°F to kill the virus.

Correct answer: B

Rationale: The correct answer is B. The CDC guidelines recommend that healthcare workers wear gloves when coming in contact with blood or body fluids from any client since HIV can be infectious before the client becomes aware of their exposure and/or symptomatic. Choice A is incorrect because placing HIV-positive clients in strict isolation and limiting visitors is not a standard practice for HIV infection control. Choice C is incorrect as mandatory HIV testing for those working with AIDS clients is not a CDC recommendation for routine infection control. Choice D is incorrect because freezing HIV blood specimens at -70°F does not kill the virus; HIV can remain infectious even at very low temperatures.

4. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Decreased pain.
• D. Increased blood viscosity.

Correct answer: A

Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.

5. A client who has just undergone surgery suddenly experiences chest pain, dyspnea, and tachypnea. The nurse suspects that the client has a pulmonary embolism and immediately sets about:

• A. Preparing the client for a perfusion scan
• B. Attaching the client to a cardiac monitor
• C. Administering oxygen via nasal cannula
• D. Ensuring that the intravenous (IV) line is patent

Correct answer: C

Rationale: When a client who has just undergone surgery experiences sudden chest pain, dyspnea, and tachypnea, indicating possible pulmonary embolism, the immediate priority for the nurse is to administer oxygen via nasal cannula. This intervention aims to improve oxygenation and alleviate respiratory distress, which is crucial in the setting of a potential pulmonary embolism. Preparing the client for a perfusion scan is not the immediate priority as stabilizing the client's respiratory status comes first. While attaching the client to a cardiac monitor is important for monitoring, administering oxygen takes precedence in this situation. Ensuring IV line patency is relevant for overall client care but is not the priority when a client is experiencing respiratory distress requiring immediate intervention.
