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. An adult female client is admitted to the psychiatric unit with a diagnosis of major depressive disorder. The nurse notices the client has more energy and is giving her belongings away. Which intervention is best for the nurse to implement?
- A. Support the client by praising her progress.
- B. Ask the client if she has had any recent thoughts of harming herself.
- C. Reassure the client about the effectiveness of antidepressant drugs.
- D. Advise the client to keep her belongings for discharge.
Correct answer: B
Rationale: The correct intervention is to ask the client if she has had any recent thoughts of harming herself because increased energy and giving away belongings can be signs of suicidal ideation. Choice A is incorrect as it does not address the potential risk of self-harm. Choice C is incorrect because reassurance about medication effectiveness may not be appropriate in this situation. Choice D is incorrect as it dismisses the client's current behavior without addressing the underlying concern of potential self-harm.
3. A client is admitted with an epidural hematoma after a skateboarding accident. How should the nurse differentiate the vascular source of intracranial bleeding?
- A. Monitor for clear fluid leakage from the nose.
- B. Assess for rapid onset of decreased level of consciousness.
- C. Check for bruising around the head and neck.
- D. Assess for changes in pupil size and reactivity.
Correct answer: B
Rationale: An epidural hematoma is characterized by a rapid onset of symptoms, including decreased level of consciousness, due to arterial bleeding, which differentiates it from other types of intracranial hemorrhage. Monitoring for clear fluid leakage from the nose (choice A) is more indicative of a basilar skull fracture and cerebrospinal fluid leak. Checking for bruising around the head and neck (choice C) is more suggestive of soft tissue injuries or facial fractures. Assessing for changes in pupil size and reactivity (choice D) is essential in evaluating traumatic brain injuries, but it is not specific to differentiating the vascular source of intracranial bleeding in an epidural hematoma.
4. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
- A. Serum potassium level
- B. Hemoglobin level
- C. White blood cell count
- D. Serum calcium level
Correct answer: A
Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.
5. The parents of a 2-month-old infant, who is being discharged after treatment for pyloric stenosis, are being educated by the healthcare provider. Which statement by the parents indicates a need for further teaching?
- A. We should feed our baby in an upright position
- B. We should avoid feeding our baby solid foods until at least 6 months of age
- C. We will lay our baby on their stomach to sleep
- D. We will burp our baby frequently during feedings
Correct answer: C
Rationale: The correct answer is C. Placing babies on their stomach to sleep increases the risk of sudden infant death syndrome (SIDS). The safest sleep position for infants is on their back to reduce the risk of SIDS. Teaching parents about safe sleep practices is crucial in preventing potential harm to the infant. Choices A, B, and D are all correct statements that promote the well-being of the infant. Feeding the baby in an upright position helps prevent reflux, delaying solid foods until 6 months of age is recommended for proper growth and development, and burping the baby frequently during feedings helps prevent gas buildup and colic.
