A nurse is caring for a client with severe anemia. The provider placed an order for one unit of packed red blood cells (PRBCs) x 1 now. The nurse should anticipate the blood will be completely infused after how much time?

8 hr

4 hr

6 hr

2 hr

Answer and Explanation

The Correct Answer is D

A. 8 hr - Infusing one unit of packed red blood cells (PRBCs) over 8 hours is too long. Typically, PRBCs are infused over a shorter period to avoid complications.

B. 4 hr - Infusing PRBCs over 4 hours is still within acceptable limits, but the standard time for PRBC transfusion is usually shorter.

C. 6 hr - Infusing PRBCs over 6 hours is longer than usual. The recommended duration for infusing one unit of PRBCs is generally shorter.

D. 2 hr - The standard time to infuse one unit of PRBCs is typically between 1.5 to 2 hours. This duration helps ensure the effective delivery of red blood cells while minimizing the risk of transfusion reactions.

Correct Answer is C

Explanation

A) Ribs: Ribs are typically not suitable for a mechanical soft diet because they are tough and require chewing. Mechanical soft diets are designed for individuals who have difficulty chewing or swallowing solid foods.

B) Apple: Apples are generally too hard and crunchy for a mechanical soft diet, which is intended to include softer, easier-to-chew foods.

C) Ground beef: Ground beef is appropriate for a mechanical soft diet because it is easier to chew and swallow compared to whole cuts of meat. It is typically tender and does not require extensive chewing.

D) Corn on the cob: Corn on the cob is not suitable for a mechanical soft diet due to its tough and fibrous texture, which can be difficult to chew and swallow for individuals on this type of diet.

A. Hyperactive bowel sounds B. muscle weakness C. Increased thirst D. Cerebral edema

Correct Answer is B

Explanation

A) Hyperactive bowel sounds:

Hyperactive bowel sounds are more commonly associated with conditions like diarrhea or gastrointestinal obstruction. Hypokalemia, or low potassium levels, typically affects muscle function rather than bowel activity directly.

B) Muscle weakness:

Muscle weakness is a key manifestation of hypokalemia. Potassium is crucial for muscle function, and a deficiency can lead to significant weakness and fatigue, which is a common symptom in individuals with low potassium levels.

C) Increased thirst:

Increased thirst is more commonly associated with dehydration or hypernatremia rather than hypokalemia. While hypokalemia can cause fluid imbalances, increased thirst is not a primary symptom of low potassium levels.

D) Cerebral edema:

Cerebral edema is not typically associated with hypokalemia. It is more commonly related to conditions such as head injury, infection, or other fluid and electrolyte imbalances. Hypokalemia primarily affects muscle function and heart rhythm.
