A nurse is caring for a client who has a potassium level of 3.2 mEq/L (3.5 to 5 mEq/L). Which of the following foods should the nurse recommend as being the best source of potassium?
1⁄2 cup apple juice
½ cup steamed cauliflower
cup boiled white rice
1 cup cantaloupe
The Correct Answer is D
Rationale:
A. ½ cup apple juice: Apple juice contains a relatively low amount of potassium, making it a poor choice for correcting hypokalemia. It typically provides less than 150 mg per half-cup serving.
B. ½ cup steamed cauliflower: Cauliflower is low in potassium compared to other vegetables. While healthy, it does not significantly contribute to raising potassium levels in the body.
C. 1 cup boiled white rice: White rice has minimal potassium content, especially when boiled. It is not effective in increasing potassium and is typically suitable for clients requiring low-potassium diets.
D. 1 cup cantaloupe: Cantaloupe is high in potassium, offering around 400–500 mg per cup. It is among the best fruit sources for replenishing potassium and is appropriate for clients with mild hypokalemia.

Correct Answer is B
Explanation
Rationale:
A. Trochanter roll: A trochanter roll is used to prevent external rotation of the hips in clients who are immobile. It does not support the feet or ankles and therefore does not prevent plantar flexion contractures.
B. Footboard: A footboard helps maintain the foot in a dorsiflexed, neutral position by providing firm support against the soles. This prevents foot drop, a common plantar flexion contracture in clients with limited mobility.
C. Sheepskin heel pad: Sheepskin heel pads protect the heels from pressure ulcers by reducing friction and shear but do not maintain ankle alignment or prevent plantar flexion of the feet.
D. Abduction pillow: An abduction pillow is placed between the legs to maintain hip alignment after procedures like hip replacement. It offers no support to the feet and does not prevent plantar flexion.
Correct Answer is A
Explanation
Rationale:
A. Apply direct pressure to the wound with thick dressing material: Direct pressure is the first-line intervention for controlling active external bleeding. Applying firm pressure with thick, sterile dressing helps tamponade the bleeding vessel and minimizes blood loss while awaiting further treatment.
B. Apply a transparent dressing to the wound: Transparent dressings are used for minor wounds or IV sites, not for managing active bleeding. They do not provide the necessary compression to control hemorrhage from a deep or penetrating injury.
C. Irrigate the wound with sterile water: Wound irrigation is appropriate for cleaning minor wounds or after bleeding is controlled. Irrigating during active bleeding can delay hemostasis and increase blood loss.
D. Tie a tourniquet around the leg distal to the wound: A tourniquet, if necessary, must be placed proximal not distal to the bleeding site to effectively restrict arterial flow. Distal placement worsens bleeding and can compromise tissue perfusion unnecessarily.
