HESI LPN
HESI Fundamentals Exam
1. A client with iron-deficiency anemia asks a nurse why the Z-track method is necessary for administering iron dextran. Which response should the nurse provide?
- A. It decreases the risk of injecting medication into a blood vessel.
- B. It delays medication absorption.
- C. It minimizes tissue irritation.
- D. It accelerates medication excretion.
Correct answer: C
Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.
2. What are some of the earliest signs and symptoms of Duchenne's muscular dystrophy?
- A. Clumsiness, difficulty running, climbing, and riding a bicycle
- B. Pain and inflammation in the bones
- C. Deformity of the foot
- D. Infection in the joint leading to arthritis
Correct answer: A
Rationale: The correct answer is A: Clumsiness, difficulty running, climbing, and riding a bicycle are some of the earliest signs and symptoms of Duchenne's muscular dystrophy. Duchenne's muscular dystrophy is a genetic disorder characterized by progressive muscle degeneration and weakness. Choices B, C, and D are incorrect because they do not represent the typical early signs and symptoms of Duchenne's muscular dystrophy. Pain and inflammation in the bones (choice B) are more indicative of conditions like osteomyelitis; deformity of the foot (choice C) is characteristic of talipes or clubfoot; and infection in the joint leading to arthritis (choice D) is more aligned with septic joint or supportive arthritis.
3. The nurse is evaluating the effectiveness of a community health program aimed at reducing teen pregnancy rates. Which outcome indicates the program was successful?
- A. increased attendance at health education classes
- B. decreased number of repeat pregnancies among teens
- C. higher number of teens seeking prenatal care
- D. greater use of contraception among teens
Correct answer: D
Rationale: The correct answer is D: greater use of contraception among teens. This outcome indicates successful prevention of pregnancies by demonstrating that teens are taking proactive steps to avoid unintended pregnancies. Increased attendance at health education classes (choice A) may show improved knowledge but does not directly measure the prevention of pregnancies. While a decreased number of repeat pregnancies among teens (choice B) is positive, it does not necessarily indicate prevention of initial pregnancies. A higher number of teens seeking prenatal care (choice C) is important for maternal and fetal health but does not directly reflect the prevention of teen pregnancies.
4. The nurse is assessing a client with portal hypertension. Which of the following findings would the nurse expect?
- A. Expiratory wheezes
- B. Blurred vision
- C. Ascites
- D. Dilated pupils
Correct answer: C
Rationale: Ascites is a common finding in clients with portal hypertension. Portal hypertension results in increased pressure in the portal vein, leading to the development of ascites, which is the accumulation of fluid in the abdominal cavity. Expiratory wheezes (Choice A) are associated with respiratory conditions. Blurred vision (Choice B) is more commonly linked to eye disorders or neurological issues. Dilated pupils (Choice D) can be related to neurological conditions or drug effects, but not specifically to portal hypertension.
5. A client with preeclampsia is receiving magnesium sulfate by continuous IV infusion. Which finding should the nurse report to the provider?
- A. Blood pressure 148/94 mm Hg
- B. Respiratory rate 14/min
- C. Urinary output 20 mL/hr
- D. 2+ deep tendon reflexes
Correct answer: C
Rationale: In a client with preeclampsia receiving magnesium sulfate, a urinary output of 20 mL/hr is a concerning finding as it may indicate renal impairment or magnesium toxicity. Adequate urinary output is crucial for eliminating excess magnesium and preventing toxicity. The nurse should report this finding to the provider for further evaluation. A blood pressure of 148/94 mm Hg is elevated but expected in a client with preeclampsia. A respiratory rate of 14/min is within the normal range. 2+ deep tendon reflexes are a common finding in clients receiving magnesium sulfate and are not a cause for concern unless they progress to hyperreflexia or clonus.
