A patient is prescribed estradiol (Estrace) for hormone replacement therapy. What should the nurse monitor during this therapy?
- A. Blood pressure
- B. Blood glucose levels
- C. Liver function tests
- D. Kidney function tests
Correct Answer: C
Rationale: During estradiol therapy, the nurse should monitor liver function tests. Estradiol can potentially impact liver function, making it essential to assess for any signs of liver dysfunction. Monitoring blood pressure (Choice A) is not directly related to estradiol therapy. While blood glucose levels (Choice B) should be monitored in patients taking certain medications like corticosteroids or antipsychotics, it is not typically necessary for patients on estradiol therapy. Kidney function tests (Choice D) are not the priority for monitoring during estradiol therapy, as the liver is more commonly affected.

A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the administration of this medication?
- A. Take the medication at the same time each day to maintain consistent hormone levels.
- B. Discontinue the medication if side effects occur.
- C. Take the medication with food to prevent gastrointestinal upset.
- D. Apply the medication once a week.
Correct Answer: A
Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.
Stress-induced cortisol hormone secretion is associated with:
- A. Increased growth hormone level
- B. Regulation of the stress response
- C. Increased thyroid-stimulating hormone
- D. Depressed adrenal gland function
Correct Answer: B
Rationale: The correct answer is B: Regulation of the stress response. Cortisol plays a crucial role in regulating the body's response to stress by modulating various physiological processes. Choices A, C, and D are incorrect because stress-induced cortisol hormone secretion is not directly associated with increased growth hormone levels, increased thyroid-stimulating hormone, or depressed adrenal gland function.
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 patient is prescribed sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?
- A. History of peptic ulcer disease
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of hypertension
Correct Answer: B
Rationale: The correct answer is B: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates combined with sildenafil can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of peptic ulcer disease, use of antihypertensive medications, or a history of hypertension are not direct contraindications for sildenafil use.
In the ED, a homeless client is brought in with severe hypothermia. The police officers also state that they found a 'bottle of booze' on the sidewalk next to him. This puts the nurse on high alert since alcohol contributes to hypothermia by:
- A. interfering with the appetite center in the brain, causing the person to not respond to hunger cues.
- B. causing the person to have less insulation from body fat.
- C. dulling mental awareness, impairing judgment to seek shelter.
- D. increasing the basal metabolic rate, leading to faster depletion of ATP.
Correct Answer: C
Rationale: Alcohol impairs judgment and dulls mental awareness, making a person less likely to seek shelter when experiencing hypothermia. This impaired judgment can lead to risky behaviors that exacerbate the effects of cold exposure. Choice A is incorrect because alcohol does not directly interfere with the appetite center in the brain to the extent described. Choice B is incorrect as alcohol consumption does not directly impact the amount of body fat present. Choice D is incorrect because alcohol does not increase the basal metabolic rate but rather slows it down.
