Nursing Elites

1. What do crackles heard on lung auscultation indicate?

• A. Cyanosis.
• B. Bronchospasm.
• C. Airway narrowing.
• D. Fluid-filled alveoli.

Correct answer: D

Rationale: Crackles heard on lung auscultation are caused by the popping open of small airways that are filled with fluid. This is commonly associated with conditions such as pulmonary edema, pneumonia, or heart failure. Cyanosis (Choice A) is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood, not directly related to crackles. Bronchospasm (Choice B) refers to the constriction of the airway smooth muscle, causing difficulty in breathing but does not typically produce crackles. Airway narrowing (Choice C) can lead to wheezing but is not directly linked to crackles heard on auscultation.

2. A middle-aged female client with diabetes mellitus is being treated for the third episode of acute pyelonephritis in the past year. The client asks, 'What can I do to help prevent these infections?' How should the nurse respond?

• A. Test your urine daily for the presence of ketone bodies and proteins.
• B. Use tampons rather than sanitary napkins during your menstrual period.
• C. Drink more water and empty your bladder more frequently during the day.
• D. Keep your hemoglobin A1c under 9% by controlling your blood sugar levels.

Correct answer: C

Rationale: The correct answer is C. Clients with long-standing diabetes mellitus are at risk for pyelonephritis due to various reasons. Elevated blood glucose levels in diabetes can lead to glucose spilling into the urine, altering the pH and creating a conducive environment for bacterial growth. Neuropathy associated with diabetes can reduce bladder tone and diminish the sensation of bladder fullness, resulting in less frequent voiding and increased risk of stasis and bacterial overgrowth. Increasing fluid intake, particularly water, and voiding regularly can help prevent stasis and microbial overgrowth. Testing urine for ketones and proteins or using tampons instead of sanitary napkins are not effective strategies for preventing pyelonephritis. Keeping the hemoglobin A1c levels below 9% is crucial for managing diabetes, but it alone does not directly prevent pyelonephritis.

3. The nurse is preparing to administer trimethoprim-sulfamethoxazole (TMP-SMX) to a patient who is being treated for a urinary tract infection. The nurse learns that the patient has type 2 diabetes mellitus and takes a sulfonylurea oral antidiabetic drug. The nurse will monitor this patient closely for which effect?

• A. Headaches
• B. Hypertension
• C. Hypoglycemia
• D. Superinfection

Correct answer: C

Rationale: When a patient takes oral antidiabetic agents (sulfonylurea) along with sulfonamides like trimethoprim-sulfamethoxazole, it can lead to an increased hypoglycemic effect. Therefore, the nurse should monitor the patient closely for hypoglycemia. Headaches, hypertension, and superinfection are not typically associated with the interaction between sulfonamides and sulfonylureas. Examples of antidiabetic sulfonylurea medications include glipizide, glimepiride, glyburide, tolazamide, and tolbutamide.

4. A nurse is assessing the status of a client with diabetes mellitus. The nurse concludes that the client is exhibiting adequate diabetic control if the serum level of glycosylated hemoglobin A1C (HbA1C) is less than:

• A. 7%
• B. 9%
• C. 10%
• D. 15%

Correct answer: A

Rationale: The correct answer is A: 7%. Glycosylated hemoglobin A1C (HbA1C) level of 7.0% or less is considered indicative of adequate diabetic control. This level reflects good long-term blood sugar management. Choices B, C, and D are incorrect because an HbA1C level above 7% indicates poor diabetic control and an increased risk of complications associated with diabetes, such as cardiovascular disease, neuropathy, and retinopathy.

5. A confused client with pneumonia is admitted with an indwelling catheter in place. During interdisciplinary rounds the following day, which question should the nurse ask the primary health care provider?

• A. Do you want daily weights on this client?
• B. Will the client be able to return home?
• C. Can we discontinue the indwelling catheter?
• D. Should we get another chest x-ray today?

Correct answer: C

Rationale: An indwelling catheter dramatically increases the risks of urinary tract infection and urosepsis. Nursing staff should ensure that catheters are left in place only as long as they are medically needed. The nurse should inquire about removing the catheter. All other questions might be appropriate, but because of client safety, this question takes priority.
