Nursing Elites

1. A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

• A. Peptic ulcer disease
• B. History of myocardial infarction
• C. Recent use of antihypertensive medications
• D. Use of nitrates

Correct answer: D

Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.

2. A male patient is being treated with testosterone gel for hypogonadism. What important instruction should the nurse provide?

• A. Apply the gel to the face and neck for maximum absorption.
• B. Apply the gel to the chest or upper arms and allow it to dry completely before dressing.
• C. Apply the gel to the scalp and back.
• D. Apply the gel to the genitals for improved results.

Correct answer: B

Rationale: The correct instruction for applying testosterone gel is to apply it to the chest or upper arms and allow it to dry completely before dressing. This is important to prevent the transfer of the medication to others. Applying it to the face and neck (Choice A) is incorrect as these areas are not recommended. Similarly, applying it to the scalp and back (Choice C) or the genitals (Choice D) is also incorrect and can lead to inappropriate absorption or undesirable effects.

3. Which of the following steps occurs first during hemostasis?

• A. Vascular spasm
• B. Platelet plug
• C. Coagulation
• D. Dissolution of the clot

Correct answer: A

Rationale: Vascular spasm is the initial step in hemostasis, where blood vessels constrict to reduce blood flow to the injured area. This constriction helps limit blood loss until further steps like platelet plug formation and coagulation can take place. Platelet plug formation and coagulation occur after the vascular spasm, making them incorrect choices. Dissolution of the clot happens much later in the healing process, after the injury has sufficiently healed.

4. How can a nurse determine the efficacy of a child's mebendazole treatment for roundworm after 3 weeks?

• A. Liver function tests
• B. Stool for ova and parasites
• C. Colonoscopy or sigmoidoscopy
• D. Rectal swab for culture

Correct answer: B

Rationale: The correct answer is B: Stool for ova and parasites. To assess the efficacy of treatment for roundworm, the nurse would examine the stool for ova (eggs) and parasites. This test helps determine if the infection has been cleared. Choices A, C, and D are incorrect because liver function tests are not commonly used to monitor roundworm treatment efficacy, and colonoscopy/sigmoidoscopy as well as rectal swab for culture are not routine diagnostic tests for assessing the effectiveness of mebendazole treatment for roundworm.

5. A nurse recalls an example of an immune-complex-mediated disease is:

• A. Bronchial asthma
• B. Contact dermatitis
• C. Serum sickness
• D. Rheumatoid arthritis

Correct answer: C

Rationale: The correct answer is C: Serum sickness. Serum sickness is characterized by the formation of immune complexes in response to certain medications or proteins. These immune complexes can deposit in tissues, leading to inflammation and tissue damage. Bronchial asthma (Choice A) is a chronic inflammatory condition of the airways not primarily mediated by immune complexes. Contact dermatitis (Choice B) is a type IV hypersensitivity reaction mediated by T cells, not immune complexes. Rheumatoid arthritis (Choice D) is an autoimmune disease where antibodies target self-antigens, but it is not primarily mediated by immune complexes.
