HESI RN
HESI Pharmacology Practice Exam
1. The client with metastatic breast cancer is receiving tamoxifen. The nurse specifically monitors which laboratory value while the client is taking this medication?
- A. Glucose level
- B. Calcium level
- C. Potassium level
- D. Prothrombin time
Correct answer: B
Rationale: The correct answer is B: Calcium level. Tamoxifen may increase calcium levels, leading to hypercalcemia. Symptoms of hypercalcemia include increased urine volume, excessive thirst, nausea, vomiting, constipation, muscle weakness, and bone pain. Monitoring serum calcium levels is essential to detect and manage this potential side effect. Choices A, C, and D are incorrect because tamoxifen does not directly affect glucose, potassium, or prothrombin time levels significantly.
2. An antibiotic IM injection for a 2-year-old child is ordered. The total volume of the injection equals 2.0 ml. The correct action is to
- A. administer the medication in 2 separate injections
- B. give the medication in the ventrogluteal site
- C. call to get a smaller volume ordered
- D. check with the pharmacy for a liquid form of the medication
Correct answer: A
Rationale: Administering the medication in 2 separate injections is the correct action. When the total volume of an injection is relatively large for a specific site, dividing it into smaller volumes and administering them separately is a safer practice to prevent discomfort, tissue damage, or absorption issues. Giving the medication in the ventrogluteal site can be appropriate for IM injections but does not address the issue of the total volume being too high for a single injection. Calling to get a smaller volume ordered may delay treatment and is not necessary when a safe administration method is available. Checking with the pharmacy for a liquid form of the medication does not directly address the issue of the total volume being too high for a single injection, and changing the formulation may not be necessary if the correct administration technique can be applied.
3. The nurse is providing discharge instructions to a client who is receiving prednisone 5 mg PO daily for a rash due to contact with poison ivy. Which symptoms should the nurse tell the client to report to the healthcare provider?
- A. Rapid weight gain
- B. Abdominal striae
- C. Moon faces
- D. Gastric irritation
Correct answer: A
Rationale: Rapid weight gain can indicate fluid retention, which is a serious side effect of prednisone and should be reported.
4. In preparing assignments for the shift, which client is best for the charge nurse to assign to a practical nurse (PN)?
- A. An older client who fell yesterday and is now complaining of diplopia.
- B. An adult newly diagnosed with type 1 diabetes and high cholesterol.
- C. A client with pancreatic cancer who is experiencing intractable pain.
- D. An older client post-stroke who is aphasic with right-sided hemiplegia.
Correct answer: D
Rationale: The best client for the charge nurse to assign to a practical nurse (PN) is an older client post-stroke who is aphasic with right-sided hemiplegia. This client is stable and suitable for care by a PN under supervision. Choices A, B, and C present clients with more complex and acute conditions that would require a higher level of nursing expertise and intervention.
5. During an admission assessment, a client informs the nurse that they take propylthiouracil (PTU) daily. Based on this information, the nurse suspects that the client has a history of:
- A. Myxedema
- B. Graves' disease
- C. Addison's disease
- D. Cushing's syndrome
Correct answer: B
Rationale: Propylthiouracil (PTU) is a medication commonly used to treat hyperthyroidism, including Graves' disease, which is characterized by an overactive thyroid gland. The client mentioning the daily use of PTU indicates that they likely have a history of Graves' disease, as this medication helps manage the condition by reducing the production of thyroid hormones. Therefore, the correct answer is B: Graves' disease. Choice A, Myxedema, is incorrect as it refers to a condition of severe hypothyroidism, the opposite of hyperthyroidism. Choices C and D, Addison's disease and Cushing's syndrome, respectively, are unrelated to the use of PTU or hyperthyroidism, making them incorrect choices.
