Adult Health 2 Exam 1

1. The nurse is caring for a client with an indwelling urinary catheter. What is the most important action to prevent catheter-associated urinary tract infections (CAUTI)?

A. Perform hand hygiene before and after handling the catheter
B. Change the catheter every 72 hours
C. Apply antibiotic ointment at the insertion site
D. Irrigate the catheter daily

Correct answer: A

Rationale: Performing hand hygiene before and after handling the catheter is crucial in preventing catheter-associated urinary tract infections (CAUTI). This practice helps minimize the risk of introducing harmful microorganisms into the urinary tract. Changing the catheter every 72 hours is not recommended unless clinically indicated as it can increase the risk of infection. Applying antibiotic ointment at the insertion site is not a standard practice and may contribute to antibiotic resistance. Irrigating the catheter daily is unnecessary and can introduce pathogens into the urinary tract, increasing the risk of infection.

2. A client is admitted with diabetic ketoacidosis. What is the most critical treatment to initiate?

A. Administer sodium bicarbonate IV
B. Start an insulin drip
C. Monitor glucose and ketone levels
D. Provide oral hydration

Correct answer: B

Rationale: In the case of diabetic ketoacidosis, the most critical treatment to initiate is starting an insulin drip. Insulin therapy is crucial for reducing blood glucose levels by promoting glucose uptake in cells and inhibiting the production of ketones. Administering sodium bicarbonate IV is generally not recommended as it may lower the pH further and potentially worsen the condition. While monitoring glucose and ketone levels is important for assessing the response to treatment, initiating insulin therapy takes precedence. Providing oral hydration alone is insufficient to manage the metabolic derangements seen in diabetic ketoacidosis.

3. What is the most important aspect of colostomy care to teach the client?

A. Change the colostomy bag only when necessary
B. Eat a low-residue diet
C. Assess the stoma for color and swelling
D. Irrigate the colostomy only if advised by a healthcare provider

Correct answer: C

Rationale: The most important aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is crucial as it ensures early detection of complications such as ischemia or infection. Changing the colostomy bag only when necessary is more appropriate than doing it daily, as it prevents unnecessary changes that may irritate the skin. While eating a low-residue diet is beneficial, it is not the most crucial aspect to teach. Irrigating the colostomy should only be done if advised by a healthcare provider, as it is not a routine procedure for all clients with a colostomy.

4. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

A. 400 mg/mL
B. 500 mg/mL
C. 450 mg/mL
D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

5. An elderly client is concerned about constipation during a flight. What should the nurse recommend?

A. Use an over-the-counter stool softener when needed
B. Eat a high protein diet
C. Increase the fluid intake in the diet
D. Decrease the fat content in the diet

Correct answer: C

Rationale: The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.
