1. After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?

A. Toasted English muffin with butter and blueberry jam, and tea with sugar
B. Two scrambled eggs, a slice of white toast, and a half cup of strawberries
C. Sausage, one slice of whole wheat toast, half cup of raisins, and a glass of milk
D. Bowl of oatmeal with brown sugar, a half cup of sliced peaches, and coffee

Correct answer: C

Rationale: Choice C is the correct answer as it includes foods high in potassium, such as raisins, whole wheat toast, and milk. Potassium is essential for various bodily functions, including maintaining proper heart and muscle function. Choices A, B, and D do not contain significant sources of potassium. Choice A consists mainly of carbohydrates and sugar, choice B focuses on protein and carbohydrates, and choice D provides carbohydrates and some fruit but lacks high-potassium options like in choice C.

2. A nurse evaluates a clients arterial blood gas values (ABGs): pH 7.30, PaO2 86 mm Hg, PaCO2 55 mm Hg, and HCO3 22 mEq/L. Which intervention should the nurse implement first?

A. Assess the airway.
B. Administer prescribed bronchodilators.
C. Provide oxygen.
D. Administer prescribed mucolytics

Correct answer: A

Rationale:

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. Which of the following is not considered an extracellular fluid?

A. Cerebrospinal fluid
B. The humors of the eye
C. Lymph
D. Cerebrospinal fluid and the humors of the eye

Correct answer: D

Rationale: The correct answer is D. Cerebrospinal fluid and the humors of the eye are not considered extracellular fluids. Extracellular fluids are fluids found outside the cells, such as interstitial fluid and lymph. Cerebrospinal fluid is found within the central nervous system, while the humors of the eye (aqueous humor and vitreous humor) are located within the eyeball, making them distinct from extracellular fluids.
