1. A client with type 1 diabetes mellitus is experiencing nausea and vomiting. What is the most important instruction the nurse should provide?
- A. Stop taking insulin until feeling better
- B. Increase fluid intake to prevent dehydration
- C. Consume high-carbohydrate foods only
- D. Check blood glucose levels frequently
Correct answer: D
Rationale: The correct answer is to instruct the client to check blood glucose levels frequently. During illness, such as nausea and vomiting, managing blood glucose levels is crucial in clients with type 1 diabetes mellitus. Monitoring blood glucose levels frequently helps in adjusting insulin doses appropriately, preventing complications like hyperglycemia or hypoglycemia. Choice A is incorrect because stopping insulin abruptly can lead to serious complications. Choice B is important but not the most critical in this scenario. Choice C is incorrect as high-carbohydrate foods may further affect blood glucose levels negatively.
2. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
3. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin?
- A. Complete blood count (CBC)
- B. Activated partial thromboplastin time (aPTT)
- C. Prothrombin time (PT)
- D. International normalized ratio (INR)
Correct answer: B
Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). This test is used to monitor the effectiveness of heparin therapy. A complete blood count (CBC) (choice A) is not specific for monitoring heparin therapy. Prothrombin time (PT) (choice C) and International normalized ratio (INR) (choice D) are more commonly used to monitor warfarin therapy, not heparin.
4. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?
- A. Prothrombin time
- B. Bleeding time
- C. Platelet count
- D. Partial thromboplastin time
Correct answer: D
Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.
5. After hospitalization for SIADH, a client develops pontine myelinolysis. Which intervention should the nurse implement first?
- A. Reorient the client to the room
- B. Place an eye patch on one eye
- C. Evaluate the client's ability to swallow
- D. Perform range of motion exercises
Correct answer: C
Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.
