PN ATI Capstone Maternal Newborn
1. Following delivery, the nurse places the newborn under a radiant heat warmer. Which of the following is this action used to prevent?
- A. Cold stress
- B. Hyperthermia
- C. Dehydration
- D. Hypoxia
Correct answer: A
Rationale: Placing the newborn under a radiant heat warmer is used to prevent cold stress. Cold stress in newborns can lead to increased oxygen consumption and energy expenditure as the body tries to maintain its temperature, potentially resulting in hypoglycemia and metabolic acidosis if not addressed. The radiant warmer helps maintain the infant's body temperature, reducing the risk of cold stress and its complications. Choices B, C, and D are incorrect because the primary purpose of using a radiant warmer in this scenario is to prevent cold stress specifically, not hyperthermia, dehydration, or hypoxia.
2. The client with a history of heart failure is receiving digoxin (Lanoxin). Which electrolyte imbalance increases the risk of digoxin toxicity?
- A. Hypernatremia
- B. Hypercalcemia
- C. Hypokalemia
- D. Hypomagnesemia
Correct answer: C
Rationale: Hypokalemia increases the risk of digoxin toxicity as low potassium levels enhance the effects of digoxin on the heart, leading to toxicity and potential adverse effects. Hypernatremia (Choice A) is not directly associated with an increased risk of digoxin toxicity. Hypercalcemia (Choice B) does not increase the risk of digoxin toxicity. Hypomagnesemia (Choice D) can contribute to digoxin toxicity, but hypokalemia has a more significant impact on increasing the risk.
3. A client who has osteoporosis is being discharged with a new prescription for alendronate. Which of the following instructions should the nurse provide?
- A. Take the medication at bedtime.
- B. Take the medication with a full glass of water.
- C. Take the medication with food.
- D. Lie down for 30 minutes after taking the medication.
Correct answer: B
Rationale: The correct answer is to take the medication with a full glass of water. Alendronate should be taken with a full glass of water to prevent esophageal irritation. Additionally, the client should remain upright for 30 minutes after taking it to prevent potential adverse effects. Choice A is incorrect because alendronate should not be taken at bedtime, but rather in the morning on an empty stomach. Choice C is incorrect because alendronate should be taken on an empty stomach, not with food. Choice D is incorrect because the client should remain upright, not lie down, for 30 minutes after taking the medication.
4. A client is receiving morphine for pain. Which of the following assessments is the priority?
- A. Urine output
- B. Pupil reaction
- C. Respiratory rate
- D. Bowel sounds
Correct answer: C
Rationale: The correct answer is C: Respiratory rate. Monitoring the respiratory rate is the priority assessment for a client receiving morphine due to the risk of respiratory depression. Morphine is a potent opioid that can cause respiratory depression, which is a serious adverse effect that can be life-threatening. Assessing the client's respiratory rate is crucial to detect any signs of respiratory depression early and intervene promptly. Assessing urine output is important but not as critical as monitoring for respiratory depression with morphine. Pupil reaction and bowel sounds are also important assessments but do not take precedence over monitoring the respiratory rate when a client is on morphine.
5. A nurse is providing care for a client with dementia who frequently wanders. What is the best strategy to ensure their safety?
- A. Use restraints to prevent wandering
- B. Encourage the client to walk in a monitored area
- C. Place a bed exit alarm system
- D. Ask family members to stay with the client at all times
Correct answer: C
Rationale: The best strategy to ensure the safety of a client with dementia who frequently wanders is to place a bed exit alarm system. This system alerts staff when the client attempts to leave the bed, reducing the risk of falls. Choice A, using restraints, is not the best approach as it can lead to complications and is not recommended unless absolutely necessary. Choice B, encouraging the client to walk in a monitored area, may not be effective in preventing wandering as the client may still wander away. Choice D, asking family members to stay with the client at all times, may not be feasible or practical, especially for round-the-clock supervision.
