The nurse is caring for the client with cardiac and renal disease. The client now has a serum potassium level of 6.0 mEq/L. Which medications, if prescribed, should the nurse administer? Select all that apply.
Calcium gluconate 1.5 grams IV now
Dextrose 50% injection (50ml) IV push now
Colace 100 mg PO now
Regular insulin 10 units IV now
Potassium chloride 20 mEq orally now
Correct Answer : A,B,D
A) Calcium gluconate 1.5 grams IV now: Calcium gluconate is administered to counteract the effects of hyperkalemia by stabilizing the myocardial cell membrane. It does not lower potassium levels but helps protect the heart from potential dysrhythmias associated with high potassium levels.
B) Dextrose 50% injection (50ml) IV push now: Dextrose 50% injection, also known as D50W, is administered to temporarily shift potassium from the extracellular space into the intracellular space, thereby lowering serum potassium levels. It is commonly used in combination with insulin to facilitate the movement of potassium into cells.
C) Colace 100 mg PO now: Colace is a stool softener and does not affect serum potassium levels. It is not indicated for the treatment of hyperkalemia.
D) Regular insulin 10 units IV now: Regular insulin is administered with dextrose to facilitate the movement of potassium from the extracellular space into the intracellular space. Insulin stimulates the cellular uptake of glucose, which in turn drives potassium into cells along with glucose.
E) Potassium chloride 20 mEq orally now: Potassium chloride is contraindicated in the treatment of hyperkalemia as it would further increase serum potassium levels. It is typically used to supplement potassium in clients with hypokalemia, not hyperkalemia.

Correct Answer is B
Explanation
A. Functional incontinence: Functional incontinence occurs when a person has difficulty reaching the toilet due to physical or cognitive impairments, such as mobility issues or dementia. Kegel exercises, which focus on strengthening the pelvic floor muscles, would not directly address the underlying causes of functional incontinence.
B. Stress incontinence: Stress incontinence is characterized by the involuntary leakage of urine during activities that increase abdominal pressure, such as coughing, sneezing, laughing, or exercising. Kegel exercises are specifically designed to strengthen the pelvic floor muscles, which can help support the bladder and reduce the occurrence of stress incontinence.
C. Urinary retention: Urinary retention refers to the inability to empty the bladder completely. While Kegel exercises may help improve bladder control, they are not typically used to address urinary retention, which often requires other interventions such as medications, catheterization, or surgery.
D. Fecal incontinence: Fecal incontinence involves the involuntary leakage of stool. Kegel exercises are not effective for addressing fecal incontinence, as they primarily target the pelvic floor muscles involved in urinary control, not bowel control. Treatment for fecal incontinence may include dietary modifications, medications, pelvic floor rehabilitation, or surgical interventions, depending on the underlying cause.
Correct Answer is B
Explanation
A) Transport the patient safely and quickly when going to the radiology department: While it's important to transport patients safely and efficiently, this action does not directly address the prevention of disease spread associated with contact precautions. Contact precautions primarily involve preventing direct or indirect contact with the patient's bodily fluids or contaminated surfaces.
B) Use a dedicated blood pressure cuff that stays in the room and is used for that patient only: This is the most appropriate action for preventing the spread of disease on contact precautions. Using dedicated equipment for the patient reduces the risk of cross-contamination between patients. It helps prevent the transmission of pathogens from one patient to another through contaminated equipment.
C) Place the patient in a room with negative airflow: Negative airflow rooms are typically used for patients on airborne precautions to prevent the spread of airborne pathogens. While maintaining appropriate airflow is important for infection control, it is not specific to contact precautions.
D) Wear a gown, gloves, face mask, and goggles for interactions with the patient: This option describes the appropriate personal protective equipment (PPE) to wear when caring for a patient on contact precautions. While it's important to wear PPE, using dedicated equipment for the patient is more directly related to preventing disease spread in this scenario
