1. Following cardiothoracic surgery where controlled therapeutic hypothermia was utilized to decrease metabolic demands, the nurse responsible for monitoring this client postoperatively should be assessing for which potential complication related to cold cardioplegia?
- A. Thrombocytopenia
- B. Hypokalemia
- C. Hyperglycemia
- D. Coagulopathy
Correct answer: D
Rationale: Coagulopathy is the correct answer. During therapeutic hypothermia, which lowers the body's temperature to reduce metabolic demands post-surgery, coagulopathy, or impaired blood clotting, is a potential complication due to the effects of cold cardioplegia. Thrombocytopenia (choice A) refers to a low platelet count and is not directly related to cold cardioplegia. Hypokalemia (choice B) is a condition of low potassium levels, and hyperglycemia (choice C) is high blood sugar levels, neither of which are primary complications of cold cardioplegia.
2. Which best describes the concept of risk?
- A. The probability that an individual will develop a specific condition
- B. The impact of a health condition on an individual's life
- C. The potential for harm from a specific condition
- D. The likelihood of being exposed to a health hazard
Correct answer: A
Rationale: The concept of risk is best described as the probability that an individual will develop a specific condition due to exposure to certain factors. It is not about the impact of a health condition on one's life (choice B), the potential harm from a specific condition (choice C), or the likelihood of being exposed to a health hazard (choice D). Understanding risk helps in assessing the chances of developing a particular health issue.
3. The nurse is teaching a group of new nursing graduates about identifiable qualities of strong families that help them function effectively. Which quality should be included in the teaching?
- A. Lack of congruence among family members
- B. Clear set of family values, rules, and beliefs
- C. Adoption of one coping strategy that always promotes positive functioning in dealing with life events
- D. Sense of commitment toward growth of individual family members as opposed to that of the family unit
Correct answer: B
Rationale: Strong families have a clear set of values, rules, and beliefs that guide their interactions and help them function effectively as a unit.
4. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the nurse report to the provider?
- A. Blood glucose level of 150 mg/dL
- B. Serum sodium level of 138 mEq/L
- C. Serum potassium level of 3.0 mEq/L
- D. Serum albumin level of 3.8 g/dL
Correct answer: C
Rationale: The correct answer is C. A serum potassium level of 3.0 mEq/L is below the normal range and indicates hypokalemia, which should be reported to the provider. Hypokalemia can lead to serious complications such as cardiac arrhythmias. Choices A, B, and D are within normal ranges and do not require immediate reporting. A blood glucose level of 150 mg/dL is slightly elevated but not critically high. A serum sodium level of 138 mEq/L is within the normal range. A serum albumin level of 3.8 g/dL is also within the normal range.
5. The parents of a child with sickle cell anemia ask why their child did not have a sickle cell crisis until he was approximately 6 months old. How should the nurse respond?
- A. Your child probably had a crisis, and you were unaware of the symptoms.
- B. Are you sure your child has sickle cell anemia and not sickle cell trait?
- C. Affected children can be asymptomatic in early infancy because of high levels of fetal hemoglobin that inhibit sickling.
- D. Have you asked your doctor about this yet?
Correct answer: C
Rationale: The correct answer is C. Fetal hemoglobin (HbF) is present in high levels during early infancy, inhibiting sickling unlike adult hemoglobin (HbS). As the levels of HbF decrease and HbS increases, the risk of sickling and crises becomes more pronounced, typically after 6 months of age. Choice A is incorrect because it assumes the crisis went unnoticed, which is not supported by medical knowledge. Choice B is incorrect as it questions the child's diagnosis rather than explaining the phenomenon of delayed crises. Choice D is incorrect as it does not provide the parents with the necessary information regarding their query.
