1. A client is admitted with diabetic ketoacidosis (DKA). Which assessment finding requires immediate intervention?
- A. Fruity breath odor.
- B. Blood glucose of 450 mg/dL.
- C. Deep, rapid respirations.
- D. Serum potassium of 5.2 mEq/L.
Correct answer: C
Rationale: The correct answer is C: Deep, rapid respirations (Kussmaul breathing). This is a sign of severe acidosis commonly seen in diabetic ketoacidosis (DKA) and requires immediate intervention. Kussmaul breathing helps to compensate for the metabolic acidosis by blowing off carbon dioxide. Prompt intervention is necessary to prevent further deterioration and potential respiratory failure. Fruity breath odor (Choice A) is a classic sign of DKA but does not require immediate intervention. While a blood glucose level of 450 mg/dL (Choice B) is high, it does not pose an immediate threat to the client's life. Serum potassium of 5.2 mEq/L (Choice D) is slightly elevated but not the most critical finding that requires immediate intervention in this scenario.
2. A client with diabetes has a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that should be prepared in the insulin syringe?
- A. 42 units
- B. 14 units
- C. 28 units
- D. 32 units
Correct answer: A
Rationale: To calculate the total number of units of insulin, you need to add the 14 units of regular insulin to the 28 units of NPH insulin, which equals 42 units. Therefore, the nurse should prepare 42 units of insulin in the syringe for the client.
3. A patient with chronic obstructive pulmonary disease (COPD) is prescribed ipratropium. What is the primary action of this medication?
- A. Reduce inflammation
- B. Relieve bronchospasm
- C. Suppress cough
- D. Thin respiratory secretions
Correct answer: B
Rationale: Ipratropium is an anticholinergic bronchodilator that primarily works to relieve bronchospasm by dilating the airways and improving airflow in patients with COPD. It does not have a significant effect on reducing inflammation, suppressing cough, or thinning respiratory secretions.
4. A 65-year-old white female with a history of arthritis, congestive heart failure, and osteoporosis complains of odynophagia for two weeks. A barium swallow shows a moderate-sized crater just above the gastroesophageal junction. What is the least likely contributor to this condition?
- A. NSAIDs
- B. Alendronate
- C. Iron sulfate
- D. Calcium channel blocker
Correct answer: D
Rationale: In this case, the least likely contributor to the condition described is the calcium channel blocker. NSAIDs, alendronate, and iron sulfate have been associated with pill-induced esophagitis, which can present with symptoms like odynophagia and erosions or ulcers on imaging studies. Pill-induced esophagitis is often due to factors like inadequate water intake with the medication, being in a supine position, or underlying motility disorders. Discontinuation of the offending medication typically leads to rapid resolution of esophageal injury. Acid-suppressive therapy may be used to prevent reflux-related damage.
5. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?
- A. Complete blood count (CBC)
- B. Prothrombin time (PT)/INR
- C. Partial thromboplastin time (PTT)
- D. Serum potassium level
Correct answer: B
Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.
