1. Which of the following measures the risk of dying from causes related to pregnancy, childbirth, and puerperium?
- A. maternal mortality
- B. neonatal death rate
- C. fetal death rate
- D. infant mortality rate
Correct answer: A
Rationale: The correct answer is A, maternal mortality. Maternal mortality specifically measures the risk of dying from pregnancy-related causes. Neonatal death rate, fetal death rate, and infant mortality rate focus on different populations and timeframes. Neonatal death rate refers to deaths within the first 28 days of life, fetal death rate measures stillbirths, and infant mortality rate includes deaths of infants under one year of age. Therefore, A is the most appropriate measure for assessing the risk of dying from causes related to pregnancy, childbirth, and puerperium.
2. When caring for premature newborns in an intensive care setting, a nurse carefully monitors oxygen concentration. What is the most common complication of this therapy?
- A. Intraventricular hemorrhage
- B. Retinopathy of prematurity
- C. Bronchopulmonary dysplasia
- D. Necrotizing enterocolitis
Correct answer: B
Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.
3. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). The nurse should monitor the client for which of the following laboratory values?
- A. Prothrombin time (PT)
- B. Serum potassium
- C. Blood urea nitrogen (BUN)
- D. White blood cell count (WBC)
Correct answer: A
Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.
4. The nurse is caring for a client on mechanical ventilation. When performing endotracheal suctioning, the nurse will avoid hypoxia by
- A. Inserting a fenestrated catheter with a whistle tip without suction
- B. Completing the suction pass in 30 seconds with a pressure of 150 mm Hg
- C. Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass
- D. Minimizing the suction pass to 60 seconds while slowly rotating the lubricated catheter
Correct answer: C
Rationale: Hyperoxygenating the client before and after suctioning helps prevent hypoxia by ensuring adequate oxygen levels during the procedure, which briefly interrupts the client's normal breathing pattern. Choice A is incorrect because inserting a fenestrated catheter with a whistle tip without suction would not prevent hypoxia. Choice B is incorrect as completing the suction pass in 30 seconds with a pressure of 150 mm Hg may lead to hypoxia. Choice D is incorrect as minimizing the suction pass to 60 seconds may not provide enough time for effective suctioning and could lead to hypoxia.
5. The nurse is assessing a newborn the day after birth. A high-pitched cry, irritability, and lack of interest in feeding are noted. The mother signed her own discharge against medical advice. What intervention is appropriate nursing care?
- A. Reduce the environmental stimuli
- B. Offer formula every 2 hours
- C. Talk to the newborn while feeding
- D. Rock the baby frequently
Correct answer: A
Rationale: The correct intervention is to reduce the environmental stimuli. In this scenario, the newborn is displaying signs of overstimulation and distress, which can be exacerbated by environmental factors. Offering formula every 2 hours (Choice B) may not address the underlying issue of overstimulation. Talking to the newborn while feeding (Choice C) and rocking the baby frequently (Choice D) may further stimulate the newborn, which is not appropriate in this case.
