HESI LPN
Adult Health 2 Final Exam
1. The healthcare provider is preparing to administer a 1.2mL injection to a 4-year-old. Which is the best site to administer an IM injection?
- A. Vastus Lateralis
- B. Radial artery
- C. Dorsogluteal
- D. Rectus femoris
Correct answer: A
Rationale: The correct answer is A, Vastus Lateralis. The vastus lateralis site is recommended for IM injections in small children due to its large muscle mass, making it suitable for injections in pediatric patients. Choices B, C, and D are incorrect. The radial artery is not a site for IM injections; it is a site for arterial puncture. The dorsogluteal site is not recommended for children due to potential risks, such as injury to the sciatic nerve. The rectus femoris is not typically used for IM injections in children, as other sites like the vastus lateralis are more commonly preferred.
2. During a routine prenatal visit, a nurse measures a client’s fundal height. The client is 26 weeks pregnant. What should the fundal height be?
- A. Approximately 26 cm
- B. Between 24 to 28 cm
- C. Above the umbilicus by two finger widths
- D. Below the xiphoid process
Correct answer: B
Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.
3. The nurse is preparing to administer an intramuscular injection to a 6-month-old infant. Which site is most appropriate for this injection?
- A. Deltoid muscle
- B. Ventrogluteal muscle
- C. Dorsogluteal muscle
- D. Vastus lateralis muscle
Correct answer: D
Rationale: The vastus lateralis muscle is the preferred site for intramuscular injections in infants due to its size and safety. The deltoid muscle is typically used for adults and older children. The ventrogluteal muscle is more commonly used in toddlers and older children. The dorsogluteal muscle is not recommended for intramuscular injections in any age group due to its proximity to major nerves and blood vessels, which poses a risk of injury or sciatic nerve damage.
4. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?
- A. Check blood pressure.
- B. Assess heart rate.
- C. Monitor respiratory rate.
- D. Measure oxygen saturation.
Correct answer: B
Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.
5. A client with a history of peptic ulcer disease (PUD) is prescribed omeprazole (Prilosec). What is the primary action of this medication?
- A. Neutralizes stomach acid
- B. Reduces gastric acid production
- C. Forms a protective barrier over ulcers
- D. Increases gastric mucus production
Correct answer: B
Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.
