1. What is the most important action for preventing infection in a client with a central venous catheter?
- A. Changing the catheter dressing every 72 hours.
- B. Flushing the catheter with heparin solution daily.
- C. Ensuring the catheter is clamped when not in use.
- D. Maintaining sterile technique when handling the catheter.
Correct answer: D
Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.
2. A client with diabetes mellitus reports feeling anxious, shaky, and weak. These findings are manifestations of which of the following complications?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Ketoacidosis
- D. Dawn phenomenon
Correct answer: B
Rationale: The correct answer is B, Hypoglycemia. In diabetes mellitus, hypoglycemia can lead to symptoms such as anxiety, shakiness, and weakness due to low blood sugar levels. Hyperglycemia (choice A) is high blood sugar levels and typically presents with symptoms like increased thirst and frequent urination. Ketoacidosis (choice C) is a serious complication of diabetes characterized by high levels of ketones in the blood, leading to symptoms such as fruity breath and rapid breathing. The Dawn phenomenon (choice D) refers to an abnormal early-morning increase in blood sugar levels without an associated hypoglycemia during the night.
3. The patient is being taught about flossing and oral hygiene. What instruction will the nurse include in the teaching session?
- A. Using waxed floss helps prevent bleeding
- B. Flossing removes plaque and tartar from the teeth
- C. Flossing at least 3 times a day is beneficial
- D. Applying toothpaste before flossing is harmful
Correct answer: B
Rationale: The correct answer is B. Flossing is essential for removing plaque and tartar between teeth, contributing to better oral hygiene. Choice A is not entirely accurate as waxed floss may not solely prevent bleeding. Flossing three times a day, as mentioned in choice C, can be excessive and unnecessary, while choice D is incorrect as applying toothpaste before flossing is not harmful but might not provide additional benefits.
4. During an abdominal assessment for an adult client, what is the correct sequence of steps?
- A. Inspect, Auscultate, Percuss, Palpate
- B. Palpate, Percuss, Inspect, Auscultate
- C. Auscultate, Inspect, Percuss, Palpate
- D. Percuss, Palpate, Inspect, Auscultate
Correct answer: A
Rationale: The correct sequence for an abdominal assessment in an adult client is to first Inspect the abdomen for any visible abnormalities, then Auscultate to listen for bowel sounds, followed by Percussion to assess for organ size and presence of fluid or masses, and finally Palpation to feel for tenderness, masses, or organ enlargement. Choice A, 'Inspect, Auscultate, Percuss, Palpate,' is the correct sequence for an abdominal assessment. Choices B, C, and D are incorrect because they do not follow the recommended sequence of assessment. Palpation should be the last step as it can potentially alter bowel sounds and percussion findings if done before. This deviation can lead to missing important findings or inaccurate assessment results.
5. A client has a sodium level of 125 mEq/L. Which of the following findings should the nurse expect?
- A. Abdominal cramping
- B. Increased thirst
- C. Elevated blood pressure
- D. Elevated heart rate
Correct answer: A
Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.
