What should the nurse teach the boy about anabolic steroid abuse?
- A. The ability of anabolic steroids to build muscle is greatly exaggerated in the media.
- B. Anabolic steroids are universally dangerous but are especially harmful to adolescents.
- C. The muscle mass resulting from steroid use will atrophy unless doses are continually increased.
- D. Anabolic steroids will reduce the boy's ability to perform weight-bearing exercise later in life.
Correct Answer: B
Rationale: The correct answer is B because anabolic steroids are indeed universally dangerous, but they pose greater risks to adolescents due to their impact on growth and development. Choice A is incorrect because anabolic steroids do have the potential to build muscle mass, though not to the extent often portrayed in the media. Choice C is incorrect as muscle mass gained from steroid use may persist for a period even after discontinuation. Choice D is incorrect as anabolic steroids can enhance muscle performance initially, though long-term use can have adverse effects on health and not specifically on the ability to perform weight-bearing exercises.

A patient is prescribed finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse include in the patient teaching regarding the expected outcomes of this therapy?
- A. The medication will cure BPH after treatment is complete.
- B. The effects of the medication may take several weeks or months to become noticeable.
- C. The medication may cause increased hair growth.
- D. The medication may decrease libido.
Correct Answer: B
Rationale: The correct answer is B. The effects of finasteride in treating BPH may take several weeks or months to become noticeable, so patients should be informed about this expected time frame. Choice A is incorrect because finasteride does not cure BPH but helps manage symptoms. Choice C is incorrect as increased hair growth is a side effect of finasteride, not an expected outcome for BPH treatment. Choice D is also incorrect as decreased libido is a potential side effect of finasteride, not an expected outcome for BPH treatment.
A 10-year-old male is stung by a bee while playing in the yard. He experiences a severe allergic reaction and has to go to the ER. The nurse providing care realizes this reaction is the result of:
- A. Toxoids
- B. IgA
- C. IgE
- D. IgM
Correct Answer: C
Rationale: The correct answer is C: IgE. A severe allergic reaction, such as the one experienced by the 10-year-old male after being stung by a bee, is mediated by IgE. IgE is involved in common allergic responses, triggering the release of histamine and other chemicals that lead to allergy symptoms. Choice A, Toxoids, are inactivated toxins used in vaccines. Choice B, IgA, is mainly found in mucosal areas and secretions, playing a role in mucosal immunity. Choice D, IgM, is the first antibody produced in response to an infection.
When preparing to administer parenteral acyclovir (Zovirax) to an 80-year-old patient with chronic renal failure and herpes simplex, what would the nurse expect in regard to the dose?
- A. The dose is smaller due to the herpes simplex infection.
- B. The dose is smaller based on the patient's kidney function.
- C. The dose is higher in treating genital herpes.
- D. The dose is higher if the creatinine clearance is above 4.0 mg/dL.
Correct Answer: B
Rationale: In patients with chronic renal failure, especially in older adults, dosages of medications excreted renally need to be adjusted based on kidney function. Acyclovir is primarily eliminated by the kidneys, so in a patient with chronic renal failure, the dose would need to be smaller to prevent drug accumulation and toxicity. Choice A is incorrect because the dose adjustment is more related to the patient's kidney function than the presence of herpes simplex. Choice C is incorrect because the type of herpes infection does not determine the dose adjustment for acyclovir. Choice D is incorrect as the creatinine clearance is a more accurate measure of kidney function compared to creatinine levels.
A patient is being educated about the use of raloxifene (Evista) for osteoporosis. What is the primary therapeutic action 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: 'It decreases bone resorption and increases bone density.' Raloxifene, a selective estrogen receptor modulator (SERM), works by decreasing bone resorption, which is the breakdown of bone, and increasing bone density. This action helps in preventing bone loss and maintaining bone strength. Choice A is incorrect because raloxifene does not stimulate the formation of new bone but rather prevents its breakdown. Choice C is incorrect as raloxifene does not increase the excretion of calcium but rather helps in maintaining calcium levels in the bones. Choice D is also incorrect as raloxifene does not directly increase calcium absorption in the intestines.
Staff at the care facility note that a woman has started complaining of back pain in recent weeks and occasionally groans in pain. She has many comorbidities that require several prescription medications. The nurse knows that which factor is likely to complicate the clinician's assessment and treatment of the client's pain?
- A. Her advanced age may influence the expression and perception of pain.
- B. Her polypharmacy may complicate the pain management process.
- C. Her underlying conditions may mask or exacerbate the pain.
- D. Her cognitive function may decline, making pain assessment difficult.
Correct Answer: B
Rationale: Polypharmacy, or the use of multiple medications, can complicate pain management due to drug interactions and side effects. While advanced age can influence pain perception, it is not the most likely factor to complicate assessment and treatment in this scenario. Underlying conditions may affect pain perception but do not directly complicate the management process. Cognitive decline can hinder pain assessment, but in this case, the focus is on factors directly impacting the treatment process, making option B the most appropriate choice.
