1. Low birth weight is defined as a newborn's weight of:
- A. 2500 grams or less at birth, regardless of gestational age.
- B. 1500 grams or less at birth, regardless of gestational age.
- C. 2500 grams or less at birth, according to gestational age.
- D. 1500 grams or less at birth, according to gestational age.
Correct answer: A
Rationale: Low birth weight is defined as 2500 grams or less at birth, regardless of gestational age. This means that any newborn weighing 2500 grams or less is considered to have a low birth weight, irrespective of how many weeks they were in the womb. Choices B, C, and D are incorrect because they specify a weight of 1500 grams or less, which is not the standard definition of low birth weight. The correct definition is 2500 grams or less, not influenced by gestational age.
2. What percentage of term newborns have a congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion?
- A. 2% to 4%
- B. 10% to 20%
- C. 5% to 10%
- D. 7% to 9%
Correct answer: A
Rationale: The correct answer is A: 2% to 4%. According to research, 2% to 4% of term newborns have congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion. Choices B, C, and D provide percentages that are higher than the actual prevalence of congenital heart disease in newborns caused by environmental factors, making them incorrect.
3. A nurse is caring for a client who is unconscious and whose partner is their health care surrogate. The partner wishes to discontinue the client's feeding tube, but another family member tells the nurse that they want the client to continue receiving treatment. Which of the following responses should the nurse make?
- A. You should contact the provider about your wishes for your family member.
- B. We'll need to have the nursing supervisor review the client's advance directives.
- C. You should speak with the facility's ethics committee about your concerns.
- D. As the health care surrogate, the client's partner can make this decision.
Correct answer: D
Rationale: The correct response is D because the health care surrogate, as designated by the client, has the legal authority to make healthcare decisions on behalf of the client when they are unable to do so. This authority includes decisions about treatment continuation or withdrawal. Option A is incorrect as the family member's wishes do not override the legal authority of the health care surrogate. Option B is not the most appropriate action in this situation as the advance directives are already clear by the designation of a health care surrogate. Option C is not necessary at this stage since the health care surrogate can make the decision without involving the ethics committee.
4. A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a sodium level of 130 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a sodium value at this level?
- A. The client with renal failure
- B. The client who is taking diuretics
- C. The client with hyperaldosteronism
- D. The client who is taking corticosteroids
Correct answer: B
Rationale: The correct answer is B. Clients taking diuretics are at risk for hyponatremia due to excessive sodium loss. In this scenario, a sodium level of 130 mEq/L indicates hyponatremia, which is commonly associated with diuretic use. Options A, C, and D are not the highest risk factors for developing low sodium levels in this context. Renal failure, hyperaldosteronism, and corticosteroid use are not directly linked to sodium loss as seen with diuretics.
5. A healthcare professional is reviewing a client's laboratory report and notes that the serum calcium level is 4.0 mg/dL. The healthcare professional understands that which condition most likely caused this serum calcium level?
- A. Prolonged bed rest
- B. Renal insufficiency
- C. Hyperparathyroidism
- D. Excessive ingestion of vitamin D
Correct answer: A
Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.
