1. Which of the following statements is correct?

Correct answer: A

Rationale: The correct statement is that people with less body fat have more body water. This is because fat tissue contains less water compared to lean tissue, so individuals with less body fat generally have a higher percentage of body water. Choice B is incorrect as infants actually have more water per pound than adults due to their higher body water content. Choice C is incorrect as males typically have more body water per pound than females. Choice D is incorrect as infants have a higher water content per pound compared to adults.

2. A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

Correct answer: A

Rationale: The correct answer is 'Depth of respirations.' In a client with electrolyte imbalances like low potassium (hypokalemia) and low magnesium (hypomagnesemia), respiratory changes, such as shallow respirations or respiratory muscle weakness, can occur and lead to respiratory compromise. Assessing the depth of respirations is crucial to evaluate respiratory function in this client. Bowel sounds, grip strength, and electrocardiography are also important assessments in different situations, but in this case, respiratory assessment takes priority due to the potential impact of electrolyte imbalances on breathing.

3. A nurse assesses a client who has a radial artery catheter. Which assessment should the nurse complete first?

Correct answer: D

Rationale:

4. You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?

Correct answer: D

Rationale: Third spacing refers to the loss of fluid from the intravascular space into the interstitial or third space, leading to a decrease in circulating blood volume. This condition results in hypovolemia, which is characterized by decreased blood volume. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly associated with third spacing. Metabolic alkalosis is an acid-base imbalance, hypermagnesemia is an excess of magnesium in the blood, and hypercalcemia is an excess of calcium in the blood, none of which are the primary concerns in cases of third spacing.

5. .A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?

Correct answer: D

Rationale:
