Question 1 of 5
A nurse is reviewing the laboratory results of a client and notes a calcium level of 7.2 mg/dL. Which of the following findings should the nurse expect?
Correct Answer: B
Rationale: The correct answer is B: Numbness of extremities. A calcium level of 7.2 mg/dL indicates hypocalcemia, which can lead to neuromuscular excitability and tingling sensations. Numbness of extremities is a common symptom of hypocalcemia due to its effect on nerve function. Hypoactive deep-tendon reflexes (choice
A) are associated with hypercalcemia, not hypocalcemia. Dry, sticky mucous membranes (choice
C) are more indicative of dehydration. Decreased bowel sounds (choice
D) may be seen in conditions affecting the gastrointestinal tract, but are not directly related to calcium levels.
Question 2 of 5
A nurse is caring for a client who has right-sided paralysis from a cerebral vascular accident (CVA). Which of the following interventions should the nurse implement?
Correct Answer: C
Rationale: The correct answer is C: Use a footboard to maintain dorsiflexion of the feet. This is important for preventing foot drop, a common issue with right-sided paralysis post-CVA. By maintaining dorsiflexion, the nurse helps prevent contractures and promotes proper alignment of the feet. A soft mattress (
A) does not address the specific issue of foot drop. Positioning soft pillows against the bottom of the feet (
B) may not provide adequate support and dorsiflexion. Crossing the client's legs at the ankles (
D) is contraindicated as it can lead to pressure ulcers and further complications.
Question 3 of 5
When a nurse obtains an unusually low blood pressure measurement for a client whose blood pressure is generally elevated, she considers the possibility of a problem with her technique. Which of the following sources of error should she consider as a possible cause of the low reading?
Correct Answer: B
Rationale: The correct answer is B: Positioning the client's arm above heart level. When the client's arm is positioned above heart level, it can lead to an artificially low blood pressure reading due to gravitational effects. This position can cause blood to pool in the arm, reducing the pressure in the arteries and resulting in an inaccurate measurement. This error is known as hydrostatic pressure error. Wrapping the cuff too loosely (choice
A) can lead to an inaccurate reading due to inadequate compression of the artery. Measuring blood pressure right after a meal (choice
C) can also affect the reading due to the body's response to food intake. Deflating the cuff too slowly (choice
D) can result in a falsely elevated diastolic reading.
Question 4 of 5
A nurse is collecting data from a client who requires bed rest and has developed thrombophlebitis. Which of the following findings should the nurse expect when examining the client's leg?
Correct Answer: D
Rationale: The correct answer is D: Edema. Thrombophlebitis is inflammation of a vein with a blood clot, leading to impaired blood flow. Edema, or swelling, is a common symptom due to the obstruction of blood flow. This results in fluid accumulation in the affected area. Cool skin, numbness, and pallor are not typical findings in thrombophlebitis. Cool skin and numbness are more indicative of nerve or circulation issues, while pallor suggests reduced blood flow but is not a common finding in thrombophlebitis.
Question 5 of 5
A nurse is collecting data from a client who has dehydration. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: The correct answer is C: Urine output 20 mL/hr. In dehydration, the body tries to conserve water, leading to decreased urine output. This finding indicates the body's attempt to retain fluids. A: Cool skin is incorrect as dehydration often presents with warm, dry skin due to decreased sweating. B: Bradycardia is unlikely in dehydration as the body tries to maintain cardiac output by increasing heart rate. D: A normal sodium level of 142 mEq/L does not specifically indicate dehydration.
