A client who weighs 132 lb receives a prescription for lorazepam 44 mcg/kg IV to be administer 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer?

(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

Convert pounds to kilograms.

1 pound = 0.453592 kilograms
132 pounds * 0.453592 kg/pound = 59.87 kilograms

Step 2: Calculate the total dose in micrograms.

44 micrograms/kilogram * 59.87 kilograms = 2635.08 micrograms

Step 3: Convert micrograms to milligrams.

1 milligram = 1000 micrograms
2635.08 micrograms / 1000 micrograms/milligram = 2.63508 milligrams

Step 4: Calculate the volume to be administered.

Concentration of lorazepam = 2 milligrams/milliliter
Volume = Dose / Concentration
Volume = 2.63508 milligrams / 2 milligrams/milliliter = 1.31754 milliliters

Therefore, the nurse should administer approximately 1.3 milliliters of the lorazepam solution.

Correct Answer is B

Explanation

Rationale

A. This intervention is crucial because bariatric surgery can have significant psychological impacts. Many individuals who undergo such procedures may experience changes in mood, body image issues, and emotional challenges. However, it is not a priority

B. Sequential compression stockings are used to prevent deep vein thrombosis (DVT) and promote circulation in clients undergoing surgery, particularly those with obesity who are at higher risk for venous thromboembolism. This intervention is important to prevent serious complications associated with immobility and surgery.

C. This option is not appropriate immediately after gastroplasty. Bariatric surgery, such as gastroplasty, typically involves restrictive procedures that limit the amount of food a person can consume. Providing a wide variety of meal choices contradicts the dietary restrictions and guidelines that are crucial for successful outcomes post-surgery.

D. While urinary incontinence can be a concern in some individuals, it is not directly related to bariatric surgery or the client's primary health concerns of obesity, diabetes mellitus, and hypertension. Monitoring for urinary incontinence may be important in other clinical contexts but is not a priority in the immediate postoperative period of gastroplasty.

A. Prepare the client for repeat blood cultures. B. Explain the need to evaluate liver function. C. Instruct the client to increase protein intake. D. Arrange emergency transport to an inpatient facility.

Correct Answer is B

Explanation

Rationale

A. Blood cultures are typically obtained to identify the causative organism of the liver abscess and to monitor the effectiveness of antimicrobial therapy. While repeat blood cultures may be considered if there is concern for ongoing infection or antimicrobial resistance, they may not be the immediate priority in the context of new-onset jaundice.

B. Jaundice indicates possible liver dysfunction, which can occur due to various reasons including progression of the liver abscess, obstruction of the bile ducts, or drug-induced liver injury from antimicrobial therapy. Evaluating liver function tests (such as serum bilirubin, liver enzymes) is essential to assess the extent of liver damage and guide further management.

C. Increasing protein intake is generally not indicated as the immediate response to jaundice. While adequate nutrition is important, specific dietary adjustments should be based on comprehensive assessment findings and medical recommendations.

D. Emergency transport to an inpatient facility may be necessary if the client shows signs of severe complications such as hemodynamic instability, worsening symptoms, or acute liver failure. However, this decision should be based on a thorough assessment of the client's condition and the availability of resources at the community clinic.
