HESI Pharmacology Practice Exam
1. A client is prescribed nitroglycerin (Nitro-Dur) transdermal patch for angina. Which instruction should the nurse include in the client's teaching plan?
- A. Apply the patch to a hairless area of skin.
- B. Leave the patch on for 24 hours.
- C. Apply the patch at the same time each day.
- D. You can keep the patch on while taking a shower.
Correct answer: C
Rationale: The correct instruction for the nurse to include in the client's teaching plan is to apply the nitroglycerin (Nitro-Dur) transdermal patch at the same time each day. This consistency helps maintain steady blood levels of the medication. While it is important to apply the patch to a hairless area of the skin for proper absorption, it does not necessarily have to be left on for 24 hours; typically, it is worn for 12-14 hours to allow for a nitrate-free period and reduce tolerance. Additionally, the patch can generally be kept on while taking a shower, as water exposure does not typically affect its efficacy.
2. A 5-week-old infant who developed projectile vomiting over the last two weeks is diagnosed with hypertrophic pyloric stenosis. Which intervention should the nurse plan to implement?
- A. Instruct the mother to give the child sugar water only.
- B. Offer oral rehydration solution every 2 hours.
- C. Provide Pedialyte feedings via nasogastric tube.
- D. Maintain intravenous fluid therapy per prescription.
Correct answer: D
Rationale: The correct intervention for a 5-week-old infant diagnosed with hypertrophic pyloric stenosis and experiencing projectile vomiting is to maintain intravenous fluid therapy. Intravenous fluids are crucial for rehydrating an infant suffering from dehydration due to rapid fluid loss from vomiting. Instructing the mother to provide sugar water only (choice A) is inappropriate and insufficient for rehydration. Offering oral rehydration solution every 2 hours (choice B) may not be effective if the infant continues to vomit. Providing Pedialyte feedings via nasogastric tube (choice C) may also not be as effective as intravenous fluid therapy in rapidly replenishing fluids and stabilizing the child's condition.
3. A client with a history of severe rheumatoid arthritis is receiving a corticosteroid. Which assessment finding should the nurse report to the healthcare provider immediately?
- A. Blood glucose level of 180 mg/dL
- B. Weight gain of 2 pounds in 24 hours
- C. Blood pressure of 140/90 mmHg
- D. Increased joint pain
Correct answer: C
Rationale: Elevated blood pressure (140/90 mmHg) is a significant finding that the nurse should report immediately. Hypertension can be a severe side effect of corticosteroid therapy, especially in clients with preexisting conditions like rheumatoid arthritis. It requires prompt intervention to prevent complications such as cardiovascular events. The other options, while important to monitor, are not as critical as elevated blood pressure in this context. A blood glucose level of 180 mg/dL may indicate hyperglycemia, weight gain could be due to fluid retention, and increased joint pain is expected in a client with severe rheumatoid arthritis.
4. At 35 weeks gestation, a client complains of 'pain whenever the baby moves.' The nurse notes a temperature of 101.2 F (38.4 C) with severe abdominal or uterine tenderness on palpation. What condition do these findings indicate?
- A. Round ligament strain.
- B. Chorioamnionitis.
- C. Abruptio placentae.
- D. Viral infection.
Correct answer: B
Rationale: The client's symptoms of fever and abdominal tenderness, along with the gestational age, are classic signs of chorioamnionitis, an infection of the amniotic fluid. Chorioamnionitis is a serious condition that requires prompt recognition and treatment to prevent maternal and fetal complications. Round ligament strain (Choice A) typically presents with sharp, stabbing pain on the sides of the abdomen and is not associated with fever or uterine tenderness. Abruptio placentae (Choice C) presents with sudden-onset vaginal bleeding and severe abdominal pain, often with a board-like uterus. Viral infections (Choice D) may present with a variety of symptoms, but the combination of fever, abdominal tenderness, and gestational age in this scenario points more towards chorioamnionitis.
5. A client with chronic renal failure is on a low-protein diet. Which of the following is the best response by the nurse when the client asks why this diet is necessary?
- A. It reduces the workload on your kidneys.
- B. It helps prevent the buildup of waste products.
- C. It helps maintain electrolyte balance in your body.
- D. It helps prevent dehydration.
Correct answer: B
Rationale: A low-protein diet is necessary for clients with chronic renal failure because it helps prevent the buildup of waste products, such as urea, in the body. Excess protein can lead to the accumulation of waste products that the compromised kidneys may not effectively filter out, further burdening the already impaired renal function. Choices A, C, and D are incorrect because the primary reason for a low-protein diet in chronic renal failure is to reduce the workload on the kidneys by minimizing the production of waste products that can exacerbate the condition, not specifically to reduce kidney workload, maintain electrolyte balance, or prevent dehydration.
