Rationale: The normal range of plasma pH in the human body typically falls between 7.35 and 7.45. This range is necessary to maintain the body's acid-base balance, which is crucial for normal physiological functioning. Deviations from this range can indicate acidosis (pH < 7.35) or alkalosis (pH > 7.45), both of which can have serious health implications. Therefore, option A (7.35-7.45) represents the normal range of plasma pH among different clients.

Correct Answer: A

Rationale: When selecting a daycare facility for an infant, it is crucial to consider the health practices of the facility. The health and safety of the infant are of utmost importance, as they are more susceptible to illnesses and infections. Ensuring that the daycare facility follows proper hygiene practices, has clean and sanitized environments, implements illness policies, and promotes healthy habits is essential in protecting the infant's well-being.

Rationale: Addison's disease is a condition characterized by adrenal insufficiency, resulting in a deficiency of aldosterone and cortisol. Without aldosterone, the body is unable to regulate fluid and electrolyte balance properly, leading to sodium loss and potassium retention. This imbalance can result in excessive fluid volume, as the kidneys retain water and sodium. Symptoms of excessive fluid volume in Addison's disease can include edema, weight gain, and hypertension. Therefore, the most appropriate nursing diagnosis for a client with Addison's disease would be Excessive Fluid Volume.

Correct Answer: B

Rationale: Transposition of the great vessels is a cyanotic congenital heart defect where the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. This results in two separate circulatory systems - one for oxygenated blood and another for deoxygenated blood. Due to this abnormal circulation, babies with transposition of the great vessels may present with severe cyanosis soon after birth. They can also develop tachypnea and tachycardia as compensatory mechanisms to maintain oxygen delivery. A STAT echocardiogram would confirm the diagnosis by showing the abnormal connection of the great vessels.
