1. On the advice of his brother, a 53-year-old man has made an appointment to request a prescription for Viagra. The nurse who works at the clinic is reviewing the man's medical history and would recognize what health problem as being prohibitive to this treatment?
- A. Type 2 diabetes, treated with metformin
- B. Hypercholesterolemia, treated with simvastatin
- C. Angina, treated with nitroglycerin
- D. Hypertension, treated with metoprolol
Correct answer: C
Rationale: Nitroglycerin is contraindicated with Viagra due to their combined effects on lowering blood pressure, which can result in a severe drop and potentially life-threatening complications. Using both medications together can lead to hypotension, putting the patient at risk. Therefore, the presence of angina treated with nitroglycerin would make prescribing Viagra unsafe. Choices A, B, and D are not directly contraindicated with Viagra and can be managed concurrently with this treatment.
2. When a child jumps out of the tub, crying and stating her feet are 'burning,' what pathophysiologic principle is responsible for this response?
- A. Pain receptors (nociceptors) have been activated in response to a thermal stimulus.
- B. The child's skin thermal receptors have undergone adaptation.
- C. The child is exhibiting a psychogenic pain response due to anxiety.
- D. The child is experiencing a conditioned pain response based on previous experiences.
Correct answer: A
Rationale: The child's reaction is due to the activation of nociceptors, which are pain receptors that respond to thermal stimuli. This response is an immediate protective mechanism to prevent tissue damage caused by extreme temperatures. Option B is incorrect because adaptation does not explain the child's immediate and intense response. Option C is incorrect as there is a clear physical stimulus present, ruling out a psychogenic response. Option D is incorrect as the child's response is not based on previous experiences but rather on the current thermal stimulus.
3. A nurse is teaching a class about immune deficiencies, and a person from the audience asks which cells are affected by severe combined immune deficiency (SCID) syndrome, and the nurse answers:
- A. B cell deficits
- B. T cell deficits
- C. Complement deficits
- D. B and T cell deficits
Correct answer: D
Rationale: The correct answer is D: B and T cell deficits. Severe combined immune deficiency (SCID) syndrome affects both B and T cells, leading to a severe impairment in the immune system's ability to fight infections. Choice A (B cell deficits) is incorrect because SCID affects not only B cells but also T cells. Choice B (T cell deficits) is incorrect as SCID is characterized by deficits in both B and T cells. Choice C (Complement deficits) is incorrect as SCID primarily involves B and T cell deficiencies rather than complement deficiencies.
4. A male patient receiving androgen therapy is concerned about the risk of prostate cancer. What should the nurse explain about this risk?
- A. Finasteride has been shown to lower the risk of developing prostate cancer.
- B. Finasteride does not affect the risk of prostate cancer, so regular screening is unnecessary.
- C. Finasteride may increase the risk of developing prostate cancer, so regular screenings are recommended.
- D. Finasteride has no effect on the risk of prostate cancer, so regular screenings are unnecessary.
Correct answer: A
Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. However, regular screenings are still recommended to monitor for any potential issues. Choice B is incorrect because finasteride has been associated with a decreased risk of prostate cancer, making regular screenings important. Choice C is incorrect as finasteride is not known to increase the risk of developing prostate cancer. Choice D is incorrect as finasteride has shown a protective effect against prostate cancer, but regular screenings are still necessary to ensure early detection and monitoring.
5. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?
- A. It usually occurs with a headache.
- B. Pupillary changes are common.
- C. It is usually triggered when the patient bends forward.
- D. Nystagmus continues even when the eyes fixate on an object.
Correct answer: C
Rationale: The correct answer is C: 'It is usually triggered when the patient bends forward.' Benign positional vertigo is often triggered by changes in head position, such as bending forward. Choices A, B, and D are incorrect. A is incorrect because benign positional vertigo is not typically associated with headaches. B is incorrect because pupillary changes are not a common feature of benign positional vertigo. D is incorrect because nystagmus in benign positional vertigo usually stops when the eyes fixate on an object.
