HESI RN
Maternity HESI 2023 Quizlet
1. Immediately after birth, a newborn infant is suctioned, dried, and placed under a radiant warmer. The infant has spontaneous respirations, and the nurse assesses an apical heart rate of 80 beats/minute and respirations of 20 breaths/minute. What action should the nurse take next?
- A. Initiate positive pressure ventilation.
- B. Intervene after the one-minute Apgar assessment.
- C. Initiate CPR on the infant.
- D. Assess the infant's blood glucose level.
Correct answer: A
Rationale: A heart rate below 100 bpm in a newborn indicates bradycardia and requires intervention. Positive pressure ventilation should be initiated to improve oxygenation and help increase the infant's heart rate. This intervention is crucial to support the newborn's transition to extrauterine life and prevent further complications.
2. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?
- A. Serum creatine kinase (CK)
- B. Serum troponin
- C. Serum myoglobin
- D. C-reactive protein (CRP)
Correct answer: B
Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.
3. A client with atrial fibrillation is prescribed warfarin, and their INR is elevated. What is the nurse's priority action?
- A. Administer a dose of vitamin K to reverse the effects of warfarin.
- B. Monitor the client for signs of bleeding, such as bruising or nosebleeds.
- C. Increase the client’s warfarin dosage to prevent clot formation.
- D. Notify the healthcare provider immediately and hold the next dose of warfarin.
Correct answer: D
Rationale: An elevated INR in clients taking warfarin increases the risk of bleeding, indicating the dose may be too high. The nurse's priority action is to notify the healthcare provider immediately and hold the next dose of warfarin to prevent bleeding complications. Administering vitamin K is not the first-line intervention for an elevated INR. Monitoring for signs of bleeding is important but not the priority over contacting the healthcare provider. Increasing the warfarin dosage can exacerbate the risk of bleeding and is contraindicated.
4. Which of the following is a key symptom of hyperthyroidism?
- A. Weight loss.
- B. Weight gain.
- C. Tachycardia.
- D. Dry skin.
Correct answer: A
Rationale: The correct answer is weight loss. In hyperthyroidism, there is an excess production of thyroid hormones leading to an increased metabolic rate. This increased metabolism can result in weight loss despite normal or increased appetite. Choice B (Weight gain) is more commonly associated with hypothyroidism where the metabolic rate is decreased. Choice C (Tachycardia) is another common symptom of hyperthyroidism due to the effects of thyroid hormones on the heart, causing an increased heart rate. Choice D (Dry skin) is not a typical symptom of hyperthyroidism; instead, it is more commonly associated with hypothyroidism.
5. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct answer: C
Rationale: The correct answer is C. The use of accessory muscles is most concerning in a client with COPD receiving supplemental oxygen as it indicates increased work of breathing, requiring immediate intervention. Oxygen saturation of 90% is acceptable in a client with COPD. A respiratory rate of 24 breaths per minute is slightly elevated but not as critical as the use of accessory muscles. Inspiratory crackles may be present in clients with COPD due to underlying lung changes but do not require immediate intervention unless associated with other concerning symptoms.
