In a patient with chronic kidney disease, which of the following lab values would be expected?
- A. Elevated creatinine levels.
- B. Low hemoglobin levels.
- C. Elevated potassium levels.
- D. Low sodium levels.
Correct Answer: A
Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.

After three days of persistent epigastric pain, a female client presents to the clinic. She has been taking oral antacids without relief. Her vital signs are heart rate 122 beats/minute, respirations 16 breaths/minute, oxygen saturation 96%, and blood pressure 116/70. The nurse obtains a 12-lead electrocardiogram (ECG). Which assessment finding is most critical?
- A. Irregular pulse rhythm
- B. Bile-colored emesis
- C. ST elevation in three leads
- D. Complaint of radiating jaw pain
Correct Answer: C
Rationale: ST elevation in three leads is a critical finding that suggests myocardial infarction, requiring immediate attention. This finding indicates ischemia or injury to the heart muscle. Choices A, B, and D are not as critical in this scenario. Irregular pulse rhythm may be concerning but does not indicate an immediate life-threatening condition like myocardial infarction. Bile-colored emesis and complaint of radiating jaw pain are relevant but not as indicative of a myocardial infarction as ST elevation in three leads.
How can a nurse best help a client undergoing a bone marrow aspiration and biopsy, along with two upset family members, manage anxiety during the procedure?
- A. Allow the client's family to stay for emotional support.
- B. Accompany the client silently.
- C. Encourage the client to take slow, deep breaths to promote relaxation.
- D. Provide the client an opportunity to verbalize emotions.
Correct Answer: C
Rationale: Encouraging the client to take slow, deep breaths is an effective way for the nurse to help the client manage anxiety during the bone marrow aspiration and biopsy procedure. Slow, deep breathing can promote relaxation and help reduce anxiety levels. Choice A, allowing the client's family to stay for emotional support, may provide comfort but does not address a direct intervention to help manage anxiety. Choice B, staying with the client silently, may not actively help the client address their anxiety. Choice D, allowing the client to express feelings, is important but may not directly address anxiety management during the procedure.
Which of the following is a sign of hypocalcemia?
- A. Hyperactive reflexes.
- B. Depressed reflexes.
- C. Muscle cramps.
- D. Seizures.
Correct Answer: A
Rationale: Hyperactive reflexes are a classic sign of hypocalcemia. Hypocalcemia leads to increased neuromuscular excitability, resulting in hyperactive reflexes. Depressed reflexes (Choice B) are not typically associated with hypocalcemia. Muscle cramps (Choice C) can be seen in hypocalcemia due to muscle irritability but are not a specific sign. Seizures (Choice D) can occur in severe cases of hypocalcemia but are not as common as hyperactive reflexes.
The client had a thyroidectomy 24 hours ago and reports experiencing numbness and tingling of the face. Which intervention should the nurse implement?
- A. Open and prepare the tracheostomy kit.
- B. Inspect the neck for an increase in swelling.
- C. Monitor for the presence of Chvostek's sign.
- D. Assess lung sounds for laryngeal stridor.
Correct Answer: C
Rationale: The correct answer is C: Monitor for the presence of Chvostek's sign. Chvostek's sign is a clinical indicator of hypocalcemia, a common complication after thyroidectomy. Numbness and tingling around the face are associated with hypocalcemia due to potential damage to the parathyroid glands during surgery, leading to decreased calcium levels. Inspecting the neck for swelling (choice B) is important but does not directly address the presenting symptoms. Opening and preparing the tracheostomy kit (choice A) is not necessary based on the client's current symptoms. Assessing lung sounds for laryngeal stridor (choice D) is not directly related to the client's reported numbness and tingling of the face.
The healthcare provider assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?
- A. Hyperaldosteronism causing increased sodium transport ion in renal tubules
- B. Decreased portacaval pressure with greater collateral circulation
- C. Decreased renin-angiotensin response related to increased renal blood flow
- D. Hypoalbuminemia that results in decreased colloidal oncotic pressure
Correct Answer: D
Rationale: In clients with cirrhosis, hypoalbuminemia leads to decreased colloidal oncotic pressure. This reduction in oncotic pressure contributes to the development of edema in the feet and legs (pitting edema) and ascites in the abdomen. Hyperaldosteronism (choice A) would lead to sodium retention but is not the primary mechanism behind edema and ascites in cirrhosis. Decreased portacaval pressure with greater collateral circulation (choice B) is not directly related to the pathophysiology of edema and ascites in cirrhosis. Decreased renin-angiotensin response related to increased renal blood flow (choice C) does not play a significant role in the development of edema and ascites in cirrhosis compared to the impact of hypoalbuminemia on colloidal oncotic pressure.
