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.

A patient has been prescribed raloxifene (Evista) for the prevention of osteoporosis. What effect should the nurse include in the teaching plan regarding the action of this medication?
- A. Decreases calcium excretion by the kidneys.
- B. Increases intestinal absorption of calcium.
- C. Stimulates bone formation by increasing osteoblast activity.
- D. Selectively binds to estrogen receptors, decreasing bone resorption.
Correct Answer: D
Rationale: The correct answer is D: Selectively binds to estrogen receptors, decreasing bone resorption. Raloxifene is a selective estrogen receptor modulator (SERM) that works by binding to estrogen receptors, thereby decreasing bone resorption. This action helps in the prevention and treatment of osteoporosis by preserving bone density. Choices A, B, and C are incorrect because raloxifene does not directly affect calcium excretion by the kidneys, intestinal absorption of calcium, or stimulate bone formation by increasing osteoblast activity.
A college student has a TB test prior to starting the semester. The tuberculin test site is noted with a reddened, raised area. What condition will the student be diagnosed with if the chest radiograph is negative?
- A. Transmission
- B. Primary infection
- C. Latent tuberculosis
- D. Active tuberculosis
Correct Answer: C
Rationale: If the chest radiograph is negative despite a positive tuberculin skin test, the student will be diagnosed with latent tuberculosis infection. Latent tuberculosis means the student has the TB bacteria in their body but does not feel sick and cannot spread the disease. Choice A, 'Transmission,' is incorrect as it refers to the spread of TB from person to person. Choice B, 'Primary infection,' is incorrect because primary infection occurs when a person is first infected with the TB bacteria. Choice D, 'Active tuberculosis,' is incorrect as this refers to the active form of the disease where the person feels sick and can spread TB to others.
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.
A 30-year-old male is being treated with testosterone enanthate for delayed puberty. What side effect should the nurse inform the patient about?
- A. Increased libido
- B. Decreased muscle mass
- C. Breast tenderness
- D. Increased aggression
Correct Answer: D
Rationale: The correct side effect that the nurse should inform the patient about when receiving testosterone enanthate therapy for delayed puberty is increased aggression. Testosterone therapy can lead to mood changes, including increased aggression in some individuals. Therefore, it is essential for healthcare providers to educate patients about this potential side effect. Choices A, B, and C are incorrect because testosterone therapy is more likely to increase libido, promote muscle mass growth, and may cause breast tenderness due to hormonal imbalances.
The nurse knows which phenomenon listed below is an accurate statement about axonal transport?
- A. Anterograde and retrograde axonal transport allow for the communication of nerve impulses between a neuron and the central nervous system (CNS).
- B. Materials can be transported to the nerve terminal by either fast or slow components.
- C. The unidirectional nature of the axonal transport system protects the CNS against potential pathogens.
- D. Axonal transport facilitates the movement of electrical impulses but precludes the transport of molecular materials.
Correct Answer: B
Rationale: The correct answer is B. Axonal transport involves the movement of materials to the nerve terminal by either fast or slow components, which is essential for cell survival. Choice A is incorrect because while anterograde and retrograde axonal transport are involved in the movement of materials, they do not specifically relate to the communication of nerve impulses between a neuron and the CNS. Choice C is incorrect because the unidirectional nature of axonal transport does not primarily function to protect the CNS against pathogens. Choice D is incorrect as axonal transport is responsible for the movement of various materials, not just electrical impulses.
