1. Why is it important for a patient to take a new oral contraceptive at the same time each day?
- A. Taking the medication at the same time each day helps maintain stable hormone levels, which is critical for preventing pregnancy.
- B. Taking the medication at the same time each day reduces the risk of breakthrough bleeding.
- C. Taking the medication at the same time each day ensures consistent absorption and effectiveness.
- D. Taking the medication at the same time each day is important, but missing a dose occasionally is not a concern.
Correct answer: A
Rationale: The correct answer is A. Taking oral contraceptives at the same time each day is crucial for maintaining stable hormone levels, which is essential for the contraceptive's effectiveness in preventing pregnancy. Choice B is incorrect because the primary reason for taking the medication consistently is hormone level stability, not specifically to reduce breakthrough bleeding. Choice C is incorrect as it focuses on absorption and effectiveness, which are important but do not address the main reason for consistent timing. Choice D is incorrect because missing doses can impact contraceptive efficacy, making consistent timing essential for optimal protection.
2. A patient is taking raloxifene (Evista) for osteoporosis. What is the primary therapeutic effect of this medication?
- A. It stimulates the formation of new bone.
- B. It decreases bone resorption and increases bone density.
- C. It increases the excretion of calcium through the kidneys.
- D. It increases calcium absorption in the intestines.
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.
3. 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?
- A. Saquinavir mesylate
- B. Oseltamivir phosphate
- C. Lamivudine
- D. Ribavirin
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.
4. What clinical manifestations would the nurse expect to find in a client who is experiencing anaphylaxis?
- A. Dilated bronchioles, constriction of peripheral blood vessels, decreased capillary permeability
- B. Asthma, deep vein thrombosis, hepatic encephalopathy
- C. Narrowing of the bronchioles, dilation of the peripheral blood vessels, increased capillary permeability
- D. Left-sided heart failure, pulmonary embolism, urinary tract infection
Correct answer: C
Rationale: In anaphylaxis, the client would present with narrowing of the bronchioles, dilation of the peripheral blood vessels, and increased capillary permeability. These manifestations lead to symptoms such as difficulty breathing, low blood pressure, and swelling. Choices A, B, and D are incorrect because they do not describe the typical clinical manifestations of anaphylaxis.
5. While planning care for an elderly patient, the nurse remembers that increased age is associated with:
- A. Increased T cell function
- B. Increased immune function
- C. Increased production of antibodies
- D. Increased levels of circulating autoantibodies
Correct answer: D
Rationale: As individuals age, their immune function tends to decrease, making them more susceptible to infections and diseases. Additionally, increased age is associated with higher levels of circulating autoantibodies, which can lead to autoimmune conditions. Choice A is incorrect as aging is not typically associated with increased T cell function. Choice C is also incorrect as aging does not necessarily result in increased production of antibodies. Therefore, the correct answers are B (Decreased immune function) and D (Increased levels of circulating autoantibodies).
