HESI RN Exit Exam
1. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?
- A. 50 ml/hour
- B. 25 ml/hour
- C. 75 ml/hour
- D. 100 ml/hour
Correct answer: C
Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.
2. A 4-month-old girl is brought to the clinic by her mother because she has had a cold for 2 or 3 days and woke up this morning with a hacking cough and difficulty breathing. Which additional assessment finding should alert the nurse that the child is in acute respiratory distress?
- A. Bilateral bronchial breath sounds.
- B. Diaphragmatic breathing.
- C. A resting respiratory rate of 35 breaths per minute.
- D. Flaring of the nares.
Correct answer: D
Rationale: Flaring of the nares is a classic sign of acute respiratory distress in infants. It indicates increased work of breathing and is a visible cue that the child is struggling to breathe. This finding should alert healthcare providers to the severity of the respiratory distress and the need for prompt intervention to support the child's breathing. Choices A, B, and C are incorrect. Bilateral bronchial breath sounds are associated with conditions like pneumonia, but they do not specifically indicate acute respiratory distress. Diaphragmatic breathing is a normal breathing pattern and not a sign of distress. A resting respiratory rate of 35 breaths per minute is within the expected range for a 4-month-old infant and does not necessarily indicate acute respiratory distress.
3. The healthcare provider is developing standards of care for a client with gastroesophageal reflux disease and wants to review current evidence for practice. Which one of the following resources will provide the most helpful information?
- A. A review in the Cochrane Library.
- B. A literature search in a database, such as the Cumulative Index to Nursing and Allied Health Literature (CINAHL).
- C. An online nursing textbook.
- D. The policy and procedure manual at the healthcare agency.
Correct answer: A
Rationale: The Cochrane Library provides systematic reviews of primary research in healthcare, making it a reliable resource for evidence-based practice. Choice B, a literature search in a database like CINAHL, may also be useful but does not guarantee the same level of systematic review and reliability as the Cochrane Library. Choice C, an online nursing textbook, may offer information but might not provide the most current or evidence-based practices. Choice D, the policy and procedure manual at the healthcare agency, is unlikely to offer the comprehensive evidence-based information needed for developing standards of care.
4. A client with a history of heart failure is admitted to the hospital with worsening dyspnea. The nurse notes that the client has a productive cough with pink, frothy sputum. What action should the nurse take first?
- A. Administer oxygen
- B. Perform chest physiotherapy
- C. Elevate the head of the bed
- D. Obtain a sputum specimen
Correct answer: A
Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.
5. The patient will begin taking penicillin G procaine (Wycillin). The nurse notes that the solution is milky in color. What action will the nurse take?
- A. Call the pharmacist and report the milky color.
- B. Add normal saline to dilute the medication.
- C. Call the physician and report the milky appearance.
- D. Administer the medication as ordered by the physician.
Correct answer: D
Rationale: The correct answer is to administer the medication as ordered by the physician. Penicillin G procaine (Wycillin) is known to have a milky appearance, which is normal. The milky color should not raise concerns for the nurse as it is an expected characteristic of this medication. Calling the pharmacist (choice A) or the physician (choice C) unnecessarily would delay the administration of the medication. Adding normal saline to dilute the medication (choice B) is not appropriate and could alter the medication's effectiveness. Therefore, the nurse should proceed with administering the medication as prescribed without any further action based on its milky appearance.
