A nurse is preparing to administer nortriptyline 150 mg PO for a client who has depression. Available is chlorpromazine hydrochloride 75 mg tablets. How many tablets should the nurse administer with each dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Excessive pulmonary secretions can be a sign of airway irritation or infection rather than a direct adverse effect of oxygen therapy. It may warrant further assessment and intervention, but it is not typically attributed to oxygen therapy itself.
B. Dryness and cracking of oral mucous membranes can occur as a result of oxygen therapy. Oxygen delivered at higher concentrations or for prolonged periods can dry out mucous membranes, leading to discomfort and potential cracking.
C. Tachycardia (an elevated heart rate) can occur as a compensatory response to hypoxia or increased metabolic demands rather than as a direct adverse effect of oxygen therapy. However, if oxygen therapy leads to an overcorrection of hypoxemia, it could potentially contribute to changes in heart rate.
D. Poor skin turgor is typically a sign of dehydration or fluid imbalance, not directly related to oxygen therapy. It may be important to assess fluid status in clients receiving oxygen therapy, but poor skin turgor itself is not an adverse effect of oxygen administration.

A. Hypercalcemia can lead to muscle weakness and fatigue rather than hypotonicity. High calcium levels affect neuromuscular function, potentially causing muscle weakness and decreased muscle tone rather than increased flaccidity.
B. Chvostek's sign is a clinical sign of hypocalcemia, not hypercalcemia. It is characterized by facial muscle twitching in response to tapping the facial nerve just anterior to the ear. Therefore, a positive Chvostek's sign would not be expected in hypercalcemia.
C. Hypercalcemia can cause gastrointestinal disturbances such as constipation rather than diarrhea. High calcium levels can lead to decreased smooth muscle contractility in the intestines, resulting in constipation rather than increased motility leading to diarrhea.
D. Hypercalcemia can lead to a variety of cardiovascular effects, including arrhythmias. Tachycardia can occur as a result of increased sensitivity of the heart to catecholamines and altered electrical conductivity in hypercalcemia.
