A nurse is preparing to administer olanzapine 10 mg PO. Available is olanzapine 5 mg orally disintegrating tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Skin tenting occurs when the skin loses its elasticity due to dehydration. When gently pinched, the skin may remain elevated and return to its normal position slowly. This finding is a classic sign of dehydration and indicates that the client has lost significant fluid volume.
B. Elevated blood pressure (BP) can sometimes be associated with dehydration, especially in acute cases or when there are underlying conditions like hypovolemia. However, it is not typically a primary indicator of dehydration. Hypotension (low blood pressure) is more commonly associated with severe dehydration.
C. Red mucous membranes may indicate various conditions, including dehydration. Dehydration can lead to dryness and mucosal irritation, resulting in redness. However, red mucous membranes alone are not specific enough to reliably indicate dehydration without considering other signs and symptoms.

D. Jugular vein distention (JVD) is associated with fluid overload rather than dehydration. It occurs when there is increased pressure in the venous system, often due to heart failure or fluid retention. JVD is not typically seen in dehydrated individuals.

A. Administering tube feedings while the client is in a supine (flat on their back) position can increase the risk of aspiration. Ideally, clients should be positioned upright or at a 30-45 degree angle during and after tube feedings to reduce the risk of reflux and aspiration.
B. Flushing the NG tube with tap water after feeding is just a standard practice to prevent clogging and maintain tube patency.

C. Administering tube feedings by gravity using a syringe barrel is an appropriate method. This allows for controlled and slow administration of the feeding solution, minimizing the risk of overfeeding or complications.
D. Aspirating gastric residual before initiating tube feedings is a standard practice to assess the amount of residual contents in the stomach. However, the amount of residual aspirate that warrants intervention can vary based on institutional policies and the client's condition.
