A nurse is preparing to administer morphine 15 mg subcutaneously.

The amount available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round to the nearest tenth.

Use a leading zero if it applies. (Do not use a trailing zero)

Choice A rationale
Acetone breath is a characteristic symptom of diabetic ketoacidosis (DKA), not hyperosmolar hyperglycemic syndrome (HHS). In DKA, the body produces ketones, leading to a fruity or acetone-like breath odor. HHS, on the other hand, does not typically involve significant ketone production.
Choice B rationale
Fever can be a manifestation of HHS, often due to an underlying infection or illness that precipitates the hyperglycemic state. Infections are common triggers for HHS, leading to elevated body temperature.
Choice C rationale
Serum glucose levels of 800 mg/dL are indicative of HHS. HHS is characterized by extremely high blood glucose levels, often exceeding 600 mg/dL, without significant ketoacidosis.
Choice D rationale
Serum bicarbonate levels of 15 mEq/L are more indicative of DKA rather than HHS. In HHS, bicarbonate levels are usually within the normal range because there is no significant ketoacidosis.
Choice E rationale
Insidious onset is a hallmark of HHS. The condition develops gradually over days to weeks, unlike DKA, which has a more rapid onset.

Choice A rationale
Positioning the lower extremities so that they are touching is incorrect because it can lead to adduction of the hip, which increases the risk of dislocation. After a total hip arthroplasty, it is important to maintain proper alignment of the hip joint to prevent dislocation. Keeping the legs apart with the use of an abduction pillow or wedge is recommended to maintain proper alignment and reduce the risk of complications.
Choice B rationale

Ensuring that the client’s heels are touching the bed is incorrect because it can lead to pressure ulcers. After a total hip arthroplasty, it is important to prevent pressure on the heels by using pillows or heel protectors to elevate the heels off the bed. This helps to reduce the risk of pressure ulcers and promotes better circulation to the lower extremities.
Choice C rationale
Instructing the client to avoid movement of the affected leg is incorrect because early mobilization is important for recovery. After a total hip arthroplasty, patients are encouraged to perform gentle exercises and mobilize as soon as possible to prevent complications such as deep vein thrombosis (DVT) and to promote healing. Immobilization can lead to stiffness, muscle atrophy, and other complications.
Choice D rationale
Preventing hip flexion of the affected extremity is correct because excessive hip flexion can increase the risk of dislocation. After a total hip arthroplasty, it is important to avoid positions that involve hip flexion greater than 90 degrees, such as sitting in low chairs or bending forward excessively. Maintaining proper hip precautions helps to reduce the risk of dislocation and promotes a safe recovery.
