A nurse is preparing to administer purified protein derivative (PPD) to a client who has suspected tuberculosis. Which of the following actions should the nurse plan to take?

Correct Answer: A

Rationale: The correct answer is A: Ensure the injection produces a wheal on the skin. A wheal indicates that the PPD has been administered correctly, allowing for the proper interpretation of results. Administering the injection in the client's thigh (choice B) is not the recommended site for PPD administration; it should be administered intradermally. Using an 18-gauge needle (choice C) is unnecessary and not the standard practice for PPD administration as a smaller gauge needle is preferred for intradermal injections. Massaging the site after injection (choice D) can lead to inaccurate results by dispersing the solution, so it is important to avoid touching the site after the injection to prevent altering the test results.

Correct Answer: C

Rationale: Albuterol is the correct choice for treating acute asthma attacks because it is a short-acting bronchodilator that provides quick relief by relaxing the muscles in the airways. Beclomethasone (choice A) and Salmeterol (choice B) are long-acting medications used for controlling and preventing asthma symptoms but are not for immediate relief during an acute attack. Montelukast (choice D) is a leukotriene receptor antagonist used for asthma maintenance therapy and not for acute asthma attacks.

Correct Answer: C

Rationale: The correct answer is C: Obesity. Obesity is a significant risk factor for hypertension due to its impact on the cardiovascular system. Obesity can lead to increased blood pressure due to the additional workload placed on the heart and blood vessels. Age alone does not necessarily predispose someone to hypertension, and a family history of hypotension or a personal history of hypotension would not increase the risk of developing hypertension. Family history of hypotension is not a known risk factor for hypertension, and a history of hypotension actually indicates low blood pressure, which is the opposite of hypertension.

Correct Answer: C

Rationale: The correct instruction for administering enoxaparin is to pinch the skin before injecting. Pinching the skin helps create a proper fold for subcutaneous injections like enoxaparin, ensuring proper delivery of the medication into the subcutaneous tissue. Choice A is incorrect because enoxaparin should be administered subcutaneously, not into the muscle. Injecting it into the muscle can lead to complications. Choice B is incorrect because massaging the injection site after administration can increase the risk of bleeding or bruising due to the anticoagulant properties of enoxaparin. Choice D is incorrect as it is a general instruction and does not specifically relate to the administration of enoxaparin.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid crowded places. Immunocompromised clients undergoing chemotherapy are at a higher risk of infections, so avoiding crowded places can help reduce exposure to pathogens. Wearing a mask at home is not necessary unless someone in the household is sick. Drinking unfiltered water can introduce harmful bacteria, increasing the risk of infection. Avoiding washing hands frequently is incorrect as hand hygiene is crucial in preventing the spread of infections.
