1. DiGeorge syndrome is a primary immune deficiency caused by:
- A. Failure of B cells to mature
- B. Congenital lack of thymic tissue
- C. Failure of formed elements of blood to develop
- D. Selective IgG deficiency
Correct answer: B
Rationale: DiGeorge syndrome is caused by a congenital lack of thymic tissue, which plays a crucial role in T cell development and maturation, leading to immune deficiency. Choice A is incorrect because DiGeorge syndrome primarily affects T cells, not B cells. Choice C is incorrect as it is too broad and not specific to the thymus. Choice D is incorrect as selective IgG deficiency is a different condition unrelated to DiGeorge syndrome.
2. A 37-year-old woman has a 10 pack-year smoking history and has been using oral contraceptives for the past 2 years. The nurse should plan health education interventions knowing that this patient faces an increased risk of
- A. osteoporosis.
- B. dementia.
- C. myocardial infarction.
- D. deep vein thrombosis.
Correct answer: C
Rationale: The correct answer is C: myocardial infarction. Women aged 35 and older who smoke, especially with a history of 10 pack-years like in this case, face an increased risk of cardiovascular disorders, including myocardial infarction, when using oral contraceptives. Choice A, osteoporosis, is incorrect because smoking and oral contraceptives do not significantly increase the risk of osteoporosis. Choice B, dementia, is not directly associated with smoking, oral contraceptives, or their combination. Choice D, deep vein thrombosis, is a risk associated with oral contraceptives, especially in combination with smoking, but the highest increased risk in this case is for myocardial infarction.
3. After ingestion of cysts, how long does it take for the symptoms of giardiasis to develop?
- A. 12 to 24 hours
- B. 3 to 5 days
- C. 1 to 2 weeks
- D. 2 to 3 months
Correct answer: B
Rationale: Giardiasis symptoms typically develop 3 to 5 days after ingestion of the cysts. This timeframe aligns with the incubation period of the Giardia parasite. Choice A (12 to 24 hours) is too short for giardiasis to manifest. Choice C (1 to 2 weeks) and choice D (2 to 3 months) represent durations that are not consistent with the usual onset of symptoms in giardiasis.
4. 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.
5. In clients with a cognitive impairment disorder, the phenomenon of increased confusion in the early evening hours is called:
- A. Aphasia.
- B. Agnosia.
- C. Sundowning.
- D. Confabulation.
Correct answer: C
Rationale: The correct answer is C: Sundowning. Sundowning is a phenomenon where individuals with cognitive impairment experience increased confusion and agitation in the late afternoon or early evening. This often occurs in conditions like dementia. Choice A, Aphasia, refers to a language disorder affecting a person's ability to communicate. Choice B, Agnosia, is the inability to recognize objects. Choice D, Confabulation, is the production of false memories without the intention to deceive, often seen in conditions like Korsakoff's syndrome.
