HESI Pharmacology Practice Exam
1. A client is learning how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching?
- A. Withdraws the NPH insulin first
- B. Withdraws the regular insulin first
- C. Injects air into the NPH insulin vial first
- D. Injects an amount of air equal to the desired dose of insulin into the vial
Correct answer: A
Rationale: When mixing regular insulin with another insulin preparation, it is crucial to withdraw the regular insulin first to prevent contamination. NPH insulin should be drawn after the regular insulin to maintain the integrity of each insulin type. Therefore, if the client withdraws the NPH insulin first, it indicates the need for further teaching. Choice B is correct as withdrawing regular insulin first is the appropriate step. Choice C is incorrect as air should be injected into the vial containing the regular insulin to maintain pressure. Choice D is incorrect as injecting air equal to the desired dose of insulin into the vial is a correct step in preparing the insulin for withdrawal.
2. The client has been taking omeprazole (Prilosec) for 4 weeks. The ambulatory care nurse evaluates that the client is receiving the optimal intended effect of the medication if the client reports the absence of which symptom?
- A. Diarrhea
- B. Heartburn
- C. Flatulence
- D. Constipation
Correct answer: B
Rationale: Omeprazole, a proton pump inhibitor, is used as an antiulcer agent to reduce gastric acid secretion. The optimal intended effect of omeprazole is the relief of pain and discomfort associated with gastric irritation, commonly referred to as heartburn. Therefore, the absence of heartburn indicates that the medication is working effectively in managing the client's gastric condition.
3. A client with hyperparathyroidism has a serum calcium level of 13 mg/dL. Which medication should be prepared to administer as prescribed to the client?
- A. Calcium chloride
- B. Calcium gluconate
- C. Calcitonin (Miacalcin)
- D. Large doses of vitamin D
Correct answer: C
Rationale: The normal serum calcium level ranges from 8.6 to 10.0 mg/dL. In hypercalcemia, as seen in this client, Calcitonin (Miacalcin) is used to decrease plasma calcium levels by inhibiting bone resorption. Calcium gluconate and calcium chloride are typically used for hypocalcemia, not hypercalcemia. Large doses of vitamin D should be avoided in hypercalcemia as they can exacerbate hypercalcemia by increasing calcium absorption from the intestines.
4. A client is taking ticlopidine hydrochloride (Ticlid). The nurse tells the client to avoid which of the following while taking this medication?
- A. Vitamin C
- B. Vitamin D
- C. Acetaminophen (Tylenol)
- D. Acetylsalicylic acid (aspirin)
Correct answer: D
Rationale: Ticlopidine hydrochloride is a platelet aggregation inhibitor. Aspirin or any aspirin-containing product should be avoided as they can precipitate or aggravate bleeding by affecting platelet function and increasing the risk of bleeding complications.
5. Desmopressin acetate (DDAVP) is prescribed for the treatment of diabetes insipidus. The nurse monitors the client after medication administration for which therapeutic response?
- A. Decreased urinary output
- B. Decreased blood pressure
- C. Decreased peripheral edema
- D. Decreased blood glucose level
Correct answer: A
Rationale: Desmopressin promotes renal conservation of water by increasing the permeability of kidney collecting ducts to water, resulting in decreased urinary output. Therefore, the therapeutic response expected after administering desmopressin for diabetes insipidus is a reduction in urinary output.
