To supplement a diet with foods high in potassium, the nurse should recommend the addition of:

Correct Answer: A

Rationale: Fruits such as bananas are a good source of potassium. Potassium is an essential mineral that plays a vital role in various bodily functions, including maintaining proper muscle function, nerve transmission, and fluid balance. Bananas are easy to incorporate into the diet and provide a significant amount of potassium per serving. Other fruits high in potassium include oranges, melons, and avocados. Therefore, recommending the addition of fruits such as bananas is a suitable way to supplement a diet with foods high in potassium.

Correct Answer: B

Rationale: Glaucoma is a group of eye conditions that damage the optic nerve, usually due to high intraocular pressure (IOP). In glaucoma, there is an imbalance between the production and drainage of aqueous humor in the eye, leading to increased pressure inside the eye. This elevated pressure can cause damage to the optic nerve, which is essential for vision, resulting in vision loss. Therefore, the best description by the nurse to explain glaucoma to a patient would be that there is an increase in intraocular pressure (Choice B).

Correct Answer: A

Rationale: Elevated LDH levels are strongly associated with aggressive disease and poor prognosis.

Correct Answer: A

Rationale: Separation anxiety is the major stressor of hospitalization for these young patients. Toddlers and preschoolers are at a critical stage of development where they are developing close attachments to their primary caregivers. Being separated from their parents or primary caregivers when admitted to the hospital can lead to feelings of fear, distress, and insecurity. This separation can significantly impact their emotional well-being and overall hospital experience. Loss of control, fear of bodily injury, and fear of pain are also stressors associated with hospitalization, but separation anxiety is the primary concern for these young patients due to their developmental stage.

Correct Answer: C

Rationale: Obstruction of the airway in a patient with asthma is primarily caused by inflammation and narrowing of the airways due to a combination of factors such as thick mucus, swelling of bronchial membranes, and contraction of muscles surrounding the bronchi. Destruction of the alveolar wall is not a direct cause of airway obstruction in asthma patients; alveolar wall destruction is typically associated with conditions like emphysema. In asthma, the primary mechanisms contributing to airway obstruction are related to inflammation, mucus production, and bronchoconstriction.
