1. An influenza outbreak has spread through a long-term care residence, affecting many of the residents with severe malaise, fever, and nausea and vomiting. In an effort to curb the outbreak, the nurse has liaised with a physician to see if residents may be candidates for treatment with what drug?

Correct answer: B

Rationale: The correct answer is B: Oseltamivir phosphate. Oseltamivir is an antiviral medication used to treat influenza infections. It works by inhibiting the neuraminidase enzyme of the influenza virus, reducing the spread of the virus in the body. Saquinavir mesylate (choice A) is used in the treatment of HIV, not influenza. Lamivudine (choice C) is also an antiviral medication primarily used in the treatment of HIV and hepatitis B, not influenza. Ribavirin (choice D) is used to treat certain viral infections like hepatitis C, respiratory syncytial virus (RSV), and some viral hemorrhagic fevers, but it is not a first-line treatment for influenza.

2. During an acute asthma exacerbation, what is the priority nursing intervention for a client with asthma?

Correct answer: C

Rationale: The priority nursing intervention during an acute asthma exacerbation is to administer short-acting beta-agonists (SABAs) as prescribed. SABAs help in quickly relieving bronchospasm and are considered the first-line treatment for acute exacerbations. Administering corticosteroids, positioning the client, and obtaining a peak flow reading are important interventions but come after administering SABAs in the management of acute asthma exacerbation.

3. A patient is taking raloxifene (Evista) for osteoporosis. What is the primary therapeutic effect of this medication?

Correct answer: B

Rationale: The correct answer is B. Raloxifene, a selective estrogen receptor modulator (SERM), primarily works by decreasing bone resorption and increasing bone density. This mechanism of action helps in the prevention and treatment of osteoporosis by maintaining or improving bone strength. Choice A is incorrect because raloxifene does not directly stimulate the formation of new bone but rather helps in preserving existing bone. Choice C is incorrect because raloxifene does not increase the excretion of calcium through the kidneys; instead, it acts on bone tissue. Choice D is incorrect as raloxifene does not directly increase calcium absorption in the intestines but rather focuses on bone health.

4. In discussing sex hormone production with the patient, the nurse should describe that testosterone is normally secreted in response to

Correct answer: B

Rationale: Testosterone production is regulated by the hypothalamic-pituitary-gonadal axis. Luteinizing hormone (LH) stimulates the Leydig cells in the testes to produce testosterone. Therefore, the correct answer is B. Choice A, 'sexual arousal,' is incorrect because testosterone secretion is not directly linked to arousal but rather to hormonal stimulation. Choice C, 'ACTH release by the adrenal cortex,' is incorrect as testosterone production is not primarily regulated by adrenocorticotropic hormone (ACTH). Choice D, 'decreased cortisol levels,' is also incorrect as cortisol and testosterone are regulated by separate endocrine pathways.

5. A female patient has been diagnosed with tuberculosis and begun multiple-drug therapy. The woman has asked the nurse why it is necessary for her to take several different drugs instead of one single drug. How should the nurse best respond to the patient's question?

Correct answer: B

Rationale: The correct answer is B. Using multiple drugs in tuberculosis treatment helps prevent the development of drug-resistant TB. This approach is crucial because if the infection is not completely eradicated, the remaining bacteria may become resistant to the single drug used, making future treatments less effective. Choice A is incorrect because the use of multiple drugs is not due to uncertainty about which drug will work, but rather to address the bacteria from different angles. Choice C is incorrect as it misleads the patient about the reason for using multiple drugs. Choice D is also incorrect because the primary purpose of using multiple drugs is not to speed up treatment but to ensure effectiveness and prevent resistance.
