1. A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

A. Assess the client's dietary intake of foods high in potassium.
B. Assess the client's neuromuscular status.
C. Assess the client's fluid intake and output.
D. Read food labels to determine sodium content.

Correct answer: D

Rationale: The correct answer is to read food labels to determine sodium content. The client's sodium level is crucial to monitor as it is on the higher side (144 mEq/L), which can indicate hypernatremia. Excessive sodium intake can lead to fluid retention and other complications. Assessing dietary sodium intake can help the nurse and client make necessary adjustments to prevent further sodium imbalances. Choices A, B, and C are not the priority in this situation as the client's sodium level needs immediate attention to prevent potential complications.

2. Who would have the greatest percentage of body water?

A. an obese male
B. a nonobese male
C. a nonobese female
D. a newborn

Correct answer: D

Rationale: Newborns have a higher percentage of body water compared to adults due to their higher body fluid content. Factors such as the higher ratio of body surface area to body volume and lower body fat content contribute to this. This is why a newborn would have the greatest percentage of body water. Choices A, B, and C are incorrect because obesity and gender do not determine the percentage of body water in individuals. Therefore, the correct answer is a newborn.

3. Which electrolyte is important in the formation of the thyroid hormones?

A. Sodium
B. Iodine
C. Iron
D. Chloride

Correct answer: B

Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.

4. A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?

A. You will need to wear a sling on your arm while the device is in place
B. There is no risk of infection because sterile technique will be used during insertion.
C. . Ask all providers to vigorously clean the connections prior to accessing the device.
D. You will not be able to take a bath with this vascular access device.

Correct answer: C

Rationale:

5. When preparing a site for the insertion of an IV catheter, how should excess hair at the site be treated?

A. Leaving the hair intact
B. Shaving the area
C. Clipping the hair in the area
D. Removing the hair with a depilatory

Correct answer: C

Rationale: The correct answer is to clip the hair in the area. Excess hair at the site of IV catheter insertion should be removed because it can be a potential source of infection. Clipping the hair is preferred over shaving because shaving can cause skin abrasions, increasing the risk of infection. Using depilatories is not recommended as they can irritate the skin, which is undesirable when preparing a clean site for an invasive procedure. Therefore, clipping the hair in the area is the most appropriate and safe method to prepare the site for IV catheter insertion.
