Correct Answer: C

Rationale: The correct answer is C. Reading food labels to determine sodium content is important in managing mild hypernatremia. This allows the client to monitor and control their sodium intake, which can help prevent further elevation of sodium levels. Weighing oneself or checking the pulse does not directly address sodium intake. Choosing cooking methods like baking or grilling is more about reducing fat intake, not sodium.

Correct Answer: D

Rationale: Rationale: The correct answer is D. Hydrostatic pressure resulting from the pumping action of the heart causes water and electrolytes to move from the arterial capillary bed to the interstitial fluid. This occurs due to the force exerted by the heart's pumping action, pushing fluid out of the capillaries into the interstitial space. This process is known as filtration and is essential for maintaining fluid balance in the body. Summary of other choices: A: Active transport of hydrogen ions does not directly cause the movement of water and electrolytes between capillaries and interstitial fluid. B: The pressure in renal capillaries specifically relates to the kidneys, not the general movement of water and electrolytes in the body. C: The dissolved particles in blood do not directly contribute to the movement of water and electrolytes between capillaries and interstitial fluid.

Correct Answer: A

Rationale: The correct answer is A: "I will drink at least three glasses of milk each day." Milk is a good source of calcium and bicarbonate, which can help buffer excess acids in the body and prevent metabolic acidosis. Calcium also plays a role in maintaining the acid-base balance. Option B is incorrect because while eating well-balanced meals is important for overall health, it does not specifically address the prevention of metabolic acidosis. Option C is irrelevant to the prevention of metabolic acidosis. Option D is incorrect because avoiding salting food does not directly address the underlying issue of metabolic acidosis related to malnutrition.

Correct Answer: B

Rationale: The correct answer is B because considering potential effects on the patient's mobility is crucial when selecting a site for IV insertion. Mobility can be affected if the IV is placed in a joint area or on the dominant hand. This could limit the patient's ability to move freely during and after the procedure. Therefore, it is important to choose a site that will not hinder the patient's movement. A: Choosing a hairless site is not the most important factor when selecting a site for IV insertion. C: Having the patient hold his arm over his head before insertion is not necessary and may cause discomfort for the patient. D: Leaving the tourniquet on for at least 3 minutes is not recommended as it can lead to complications such as venous stasis.

Correct Answer: D

Rationale: To interpret the given ABG results: 1. pH <7.35 indicates acidosis. 2. PaCO2 <35 indicates respiratory alkalosis. 3. HCO3 <22 indicates metabolic acidosis. Therefore, the ABG results show metabolic acidosis (low pH, low HCO3) with compensatory respiratory alkalosis (low PaCO2). This means the body is trying to compensate for the metabolic acidosis by decreasing PaCO2 through hyperventilation. Option D is correct. Options A, B, and C are incorrect as they do not align with the ABG results and the principles of acid-base balance.
