1. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

2. The client with a diagnosis of hypertension is being taught about lifestyle changes. Which recommendation is most important to include?

• A. Increase sodium intake.
• B. Engage in regular physical activity.
• C. Avoid foods high in fat.
• D. Limit fluid intake to 1 liter per day.

Correct answer: B

Rationale: Engaging in regular physical activity is crucial for individuals with hypertension as it helps lower blood pressure and improve cardiovascular health. Physical activity is known to have a significant impact on reducing hypertension and overall cardiovascular risk. Choice A, increasing sodium intake, is incorrect as reducing sodium is typically recommended for hypertension to help lower blood pressure. Choice C, avoiding foods high in fat, is beneficial for overall health but not the most crucial recommendation for hypertension management. Choice D, limiting fluid intake to 1 liter per day, is not a standard recommendation for hypertension unless advised by a healthcare provider for specific cases. Therefore, the most important recommendation for the client with hypertension is to engage in regular physical activity.

3. When inserting an indwelling urinary catheter in a female client and urine flows into the tubing, what is the next action?

• A. Document the color and clarity of the urine
• B. Insert the catheter an additional inch
• C. Ask the client to breathe deeply and slowly exhale
• D. Inflate the balloon with 5 mL of sterile water

Correct answer: D

Rationale: When urine flows into the tubing during the insertion of an indwelling urinary catheter, it confirms proper catheter placement. The next step should be to inflate the balloon with the specified amount of sterile water to secure the catheter in place. Documenting the color and clarity of the urine (choice A) is important for assessment but not the immediate next action. Inserting the catheter further (choice B) without securing it could cause harm. Asking the client to breathe deeply (choice C) is not relevant to this situation.

4. The healthcare provider plans to assess a newborn and check the infant's Moro reflex. What is the healthcare provider evaluating?

• A. Neurological integrity
• B. Renal functioning
• C. Thermoregulation
• D. Respiratory adequacy

Correct answer: A

Rationale: The Moro reflex is an instinctive response observed in newborns, indicating their neurological integrity. This reflex is evaluated by eliciting a startle response in the infant, involving the sudden extension and abduction of the limbs, followed by their retraction. This assessment helps in determining the proper functioning of the infant's nervous system and brain. Choices B, C, and D are incorrect as they do not relate to the evaluation of the Moro reflex. Renal functioning pertains to kidney function, thermoregulation refers to temperature control, and respiratory adequacy involves assessing breathing and oxygenation levels, none of which are evaluated through the Moro reflex.

5. When reconstituted, how many milligrams are in each milliliter of solution?

• A. 300 mg/mL
• B. 350 mg/mL
• C. 450 mg/mL
• D. 400 mg/mL

Correct answer: D

Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.
