Nokea
A nurse notes that a clients eyes are protruding slightly from their orbits. Which of the following laboratory findings should the nurse expect?
- A. Decreased TSH levels
- B. Increased T4 levels
- C. Elevated calcium levels
- D. Low hemoglobin levels
Correct Answer: B
Rationale: The nurse should expect increased T4 levels in a client with slightly protruding eyes, known as exophthalmos, as it is a classic sign of hyperthyroidism, where the thyroid gland is overactive. Thyroid hormones, such as T4, are responsible for regulating metabolism, and elevated levels can lead to symptoms like exophthalmos. Decreased TSH levels (choice A) would actually be seen in primary hyperthyroidism due to negative feedback. Elevated calcium levels (choice C) are more indicative of hyperparathyroidism. Low hemoglobin levels (choice D) are not typically associated with exophthalmos or hyperthyroidism.

A nurse is assessing a client who has right-sided heart failure. Which of the following findings should the nurse identify as a manifestation of right-sided heart failure?
- A. Crackles in the lungs
- B. Increased abdominal girth
- C. Pink frothy sputum
- D. Hypertension
Correct Answer: B
Rationale: The correct answer is B: Increased abdominal girth. In right-sided heart failure, the heart is unable to efficiently pump blood to the lungs for oxygenation, leading to fluid backup in the systemic circulation. This results in fluid retention, particularly in the abdomen, causing increased abdominal girth. Crackles in the lungs (choice A) are indicative of left-sided heart failure. Pink frothy sputum (choice C) is a sign of pulmonary edema, which is a manifestation of left-sided heart failure. Hypertension (choice D) is not typically associated with right-sided heart failure.
A nurse is caring for a client who has a small bowel obstruction and an NG tube in place. Which of the following actions should the nurse take?
- A. Maintain low intermittent suction.
- B. Clamp the NG tube every 2 hours.
- C. Remove the NG tube immediately.
- D. Encourage high-fiber foods.
Correct Answer: A
Rationale: Correct Answer: A: Maintain low intermittent suction.
Rationale: Maintaining low intermittent suction helps to decompress the bowel, reducing the risk of further obstruction. Suction also helps to remove excess fluid and gas from the digestive system, providing relief to the client. It is essential to prevent excessive suction, as it can cause damage to the bowel and worsen the obstruction.
Summary of other choices:
B: Clamping the NG tube every 2 hours is not recommended as it can lead to a buildup of fluid and gas in the bowel, potentially worsening the obstruction.
C: Removing the NG tube immediately is contraindicated as it is necessary for decompression and monitoring of bowel function.
D: Encouraging high-fiber foods is inappropriate in the case of a small bowel obstruction as it can further obstruct the bowel.
A nurse is assessing a client who recently had a myocardial infarction. Which of the following findings indicates that the client might be developing pulmonary edema? (Select all that apply.)
- A. Excessive somnolence
- B. Epistaxis
- C. Pink frothy sputum
- D. Tachypnea
- E. Urinary frequency
Correct Answer: A, C, D
Rationale: The correct answers are A, C, and D. Excessive somnolence (A) can indicate inadequate oxygenation due to pulmonary edema. Pink frothy sputum (C) is a classic sign of pulmonary edema, caused by fluid leaking into the lungs. Tachypnea (D) is the body's response to decreased oxygen levels in the blood, characteristic of pulmonary edema. Epistaxis (B) and urinary frequency (E) are not typically associated with pulmonary edema. In summary, the correct answers reflect respiratory distress and inadequate oxygenation, while the incorrect choices are unrelated symptoms.
A nurse is planning care for a client who is receiving intermittent IV fluids via a peripherally inserted central catheter (PICC). Which of the following information should the nurse include in the clients plan of care?
- A. Assess the PICC infusion system systematically.
- B. Flush the line only before infusing medication.
- C. Use a sterile dressing for the catheter site every 7 days.
- D. Allow the catheter to remain uncapped when not in use.
Correct Answer: A
Rationale: The correct answer is A: Assess the PICC infusion system systematically. This is essential to monitor for signs of infection, occlusion, or dislodgement of the catheter. Regular assessment can help identify any issues early and prevent complications.
Summary:
B: Flushing the line only before infusing medication is incorrect as regular flushing is necessary to maintain catheter patency.
C: Using a sterile dressing every 7 days is incorrect as the dressing should be changed according to facility protocol or if it becomes soiled or loose.
D: Allowing the catheter to remain uncapped when not in use is incorrect as it can increase the risk of contamination and infection.
A nurse is caring for a client who has a prescription for lactated Ringers by continuous IV infusion to replace output from an NG tube. Which of the following findings should indicate to the nurse that this therapy is effective?
- A. Urine specific gravity 1.035
- B. Urine specific gravity 1.020
- C. Decreased skin turgor
- D. Dry mucous membranes
Correct Answer: B
Rationale: The correct answer is B: Urine specific gravity 1.020. This finding indicates that the kidneys are effectively concentrating urine, which means fluid balance is being maintained. A specific gravity of 1.020 is within the normal range, suggesting adequate hydration. A high specific gravity like 1.035 (choice A) indicates dehydration. Decreased skin turgor (choice C) and dry mucous membranes (choice D) are signs of dehydration, not effectiveness of therapy.
