1. Which of the following represents a normal serum potassium level?

A. 1.5 mEq/L
B. 3.0 mEq/L
C. 4.0 mEq/L
D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

A. The immune system of an infant is immature, and the infant is at risk for infection.
B. The transfer of your antibodies protects your infant until the infant is 12 months old.
C. Yes, your infant is protected from all infections.
D. If you breastfeed, your infant is protected from infection.

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

3. The goals of palliative care include all of the following except:

A. giving clients with life-threatening illnesses the best quality of life possible.
B. taking care of the whole person"?body, mind, spirit, heart, and soul.
C. no interventions are needed because the client is near death.
D. supporting the needs of the family and client.

Correct answer: C

Rationale: The correct goal of palliative care is to provide comprehensive care that addresses the physical, emotional, social, and spiritual needs of the dying client until the end of life. Therefore, the statement 'no interventions are needed because the client is near death' is incorrect as interventions are still essential to ensure comfort and quality of life. Choices A, B, and D are all aligned with the goals of palliative care, focusing on improving the quality of life, providing holistic care, and supporting both the family and the client.

4. When assessing a client's risk for elimination impairment, which of the following factors is least relevant?

A. current medications
B. ambulation abilities
C. family history
D. hydration status

Correct answer: C

Rationale: When assessing a client's risk for elimination impairment, family history is the least relevant factor to consider. Current medications can affect elimination functions through side effects, ambulation abilities can impact mobility to access toileting facilities, and hydration status directly influences urinary output and bowel function. Family history, although providing some context, does not have a direct impact on the client's current risk of elimination impairment.

5. The LPN is auscultating for bowel sounds and hears between 3 and 4 bowel sounds per minute. This is a somewhat expected finding for which of these clients?

A. a 63-year-old female undergoing chemotherapy for breast cancer
B. a 56-year-old female with dementia undergoing a swallow study
C. a 34-year-old male with a PEG tube newly admitted for diabetic ketoacidosis
D. a 45-year-old male recovering from a knee replacement under general anesthesia

Correct answer: D

Rationale: When recovering from general anesthesia, hypoactive bowel sounds can be expected due to the effects of the anesthesia on gut motility. For the other clients, hearing less than 5 bowel sounds per minute would indicate an abnormal finding. In the context of the given situation, the client recovering from knee replacement surgery aligns with the expected range of bowel sounds post-general anesthesia. Therefore, choice D is the correct answer. Choices A, B, and C present scenarios where hearing less than 5 bowel sounds per minute would be abnormal, indicating potential issues that need further evaluation.
