A client is scheduled to have a glycosylated hemoglobin (A1C) drawn and asks the nurse why she has to have it. How would the nurse respond?
- A. It measures your average blood glucose level for the past 3 months.
- B. It determines what type of anemia you may have.
- C. It measures the amount of liver glycogen you have.
- D. It determines you have some type of leukemia or other blood cancer.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. A glycosylated hemoglobin (A1C) test measures the average blood glucose level over the past 3 months.
2. It is important for monitoring and managing diabetes.
3. The test reflects long-term blood sugar control, providing valuable information about diabetes management.
4. The nurse should explain this to the client to emphasize the significance of the test in managing their health.
Summary:
B: Incorrect. A1C does not determine anemia type.
C: Incorrect. A1C does not measure liver glycogen.
D: Incorrect. A1C does not diagnose leukemia or blood cancer.

An exophthalmic goiter is a symptom of ______.
- A. Graves disease.
- B. Hashimoto's disease.
- C. myxedema.
- D. acromegaly.
Correct Answer: A
Rationale: Step-by-step rationale:
1. Exophthalmic goiter refers to bulging eyes and enlarged thyroid gland.
2. Graves disease is an autoimmune disorder causing hyperthyroidism, resulting in both symptoms.
3. Hashimoto's disease is an autoimmune disorder causing hypothyroidism, not associated with exophthalmic goiter.
4. Myxedema is severe hypothyroidism but does not typically present with exophthalmic goiter.
5. Acromegaly is caused by excess growth hormone, leading to enlarged hands and feet, not related to exophthalmic goiter.
Most endocrine organs are prodded into action by other hormones; this type of stimulus is called:
- A. hormonal stimulus
- B. humoral stimulus
- C. neural stimulus
- D. receptor-mediated stimulus
Correct Answer: A
Rationale: The correct answer is A: hormonal stimulus. Endocrine organs are typically activated by other hormones circulating in the bloodstream, triggering a chain reaction of hormonal responses. This is known as hormonal stimulus. Other choices are incorrect because humoral stimulus refers to changes in blood levels of ions or nutrients, neural stimulus involves nerve impulses, and receptor-mediated stimulus is not a recognized term in endocrine physiology.
Cells that respond to a particular hormone are called
- A. receptor cells.
- B. sensor cells.
- C. secretory cells.
- D. target cells.
Correct Answer: D
Rationale: The correct answer is D: target cells. Target cells are specific cells that have receptors for a particular hormone, allowing them to respond to the hormone's signal. These cells are the intended recipients of the hormone's message and carry out the appropriate physiological response. Receptor cells (A) are more general and can refer to any cell with receptors, not necessarily for hormones. Sensor cells (B) detect stimuli but may not necessarily respond to hormones. Secretory cells (C) release hormones rather than respond to them.
Donepezil is a reversible anti-cholinesterase used in the treatment of:
- A. Glaucoma
- B. Bradycardia
- C. Urine retention
- D. Alzheimer disease
Correct Answer: D
Rationale: Donepezil is used in the treatment of Alzheimer's disease because it is a reversible anti-cholinesterase that helps improve cognitive function by increasing levels of acetylcholine in the brain. This neurotransmitter is important for memory and learning, which are affected in Alzheimer's disease.
Choice A (Glaucoma) is incorrect because Donepezil does not treat this condition. Choice B (Bradycardia) is incorrect because Donepezil does not affect heart rate. Choice C (Urine retention) is incorrect because Donepezil does not have any impact on urinary function.
In summary, the correct answer is D (Alzheimer's disease) because Donepezil's mechanism of action aligns with the cognitive deficits seen in this condition, while the other choices are not related to the drug's pharmacological effects.
A patient with hypoparathyroidism resulting from surgical treatment of hyperparathyroidism is preparing for discharge. What should the nurse teach the patient?
- A. Milk and milk products should be increased in the diet.
- B. Parenteral replacement of parathyroid hormone will be required for life.
- C. Calcium supplements with vitamin D can effectively maintain calcium balance.
- D. Bran and whole-grain foods should be used to prevent GI effects of replacement therapy.
Correct Answer: C
Rationale: Calcium supplements with vitamin D are essential to maintain calcium balance in patients with hypoparathyroidism.
