ATI-RN Adult Medical Surgical Nursing Detailed Answer Key ATI Complex Endocrine Practice-latest Update.1. A nurse is caring for a client who is 1 day
... [Show More] postoperative following a subtotal thyroidectomy. The client reports a tingling sensation in the hands, the soles of the feet, and around the lips. For which of the following findings should the nurse assess the client?
A. Chvostek's sign
RATIONALE: The nurse should suspect that the client has hypocalcemia, a possible complication following subtotal thyroidectomy. Manifestations of hypocalcemia include numbness and tingling in the hands, the soles of the feet, and around the lips, typically appearing between 24 and 48 hr after surgery. To elicit Chvostek's sign, the nurse should tap the client's face at a point just below and in front of the ear. A positive response would be twitching of the ipsilateral (same side only) facial muscles, suggesting neuromuscular excitability due to hypocalcemia.
B. Babinski's sign
RATIONALE: Babinski's sign is a diagnostic test for brain damage or upper motor neuron damage. It is positive if the toes flare up when the nurse strokes the plantar aspect of the foot.
C. Brudzinski's sign
RATIONALE: Brudzinski's sign is an indication of meningeal irritation, such as in clients who have meningitis. With the client supine, the nurse should place one hand behind his head and places her other hand on his chest. The nurse then raises the client's head with her hand behind his head, while the hand on his chest restrains him and prevents him from rising. Flexion of the client's lower extremities constitutes a positive sign.
D. Kernig's sign
RATIONALE: Kernig's sign is an indication of meningeal irritation, such as in clients who have meningitis. The nurse performs the maneuver with the client supine with his hips and knees in flexion. The inability to extend the client's knees fully without causing pain constitutes a positive test.
2. A nurse is caring for an adolescent client who has a long history of diabetes mellitus and is being admitted to the emergency department confused, flushed, and with an acetone odor on the breath. Diabetic ketoacidosis is suspected. The nurse should anticipate using which of the following types of insulin to treat this client?
A. NPH insulin
RATIONALE: Isophane NPH insulin is intermediate-acting. It has an onset of action of 1 to 3 hr and is not appropriate for emergency treatment of ketoacidosis.
B. Insulin glargine
RATIONALE: Insulin glargine is a long-acting insulin, with an onset of 2 to 4 hr. It is not appropriate for emergency treatment of ketoacidosis.
C. Insulin detemir
RATIONALE: Insulin detemir is an intermediate-acting insulin. It has an onset of action of 1 hr and is not appropriate for emergency treatment of ketoacidosis.
D. Regular insulin
RATIONALE:

Regular insulin is classified as a short-acting insulin. It can be given intravenously with an onset of action of less than 30 min. This is the insulin that is most appropriate in emergency situations of severe hyperglycemia or diabetic ketoacidosis.
3. A nurse is assessing a client who has diabetes insipidus. Which of the following findings should the nurse expect? A. Dehydration
RATIONALE: Diabetes insipidus causes excessive excretion of dilute urine, resulting in dehydration. B. Polyphagia
RATIONALE: Polyphagia is a finding of diabetes mellitus, not insipidus.
C. Hyperglycemia
RATIONALE: Hyperglycemia is a finding of diabetes mellitus, not diabetes insipidus.
D. Bradycardia
RATIONALE: Tachycardia, not bradycardia, is a manifestation of diabetes insipidus.
4. A nurse is caring for a client who has diabetes insipidus and is receiving vasopressin. The nurse should identify which of the following findings as an indication that the medication is effective?
A. A decrease in blood sugar
RATIONALE: Blood sugar level is not affected in diabetes insipidus.
B. A decrease in blood pressure
RATIONALE: Diabetes insipidus causes the loss of large amounts of urine, which can lead to hypotension. An increase (or at least no further decrease) in blood pressure would be the desired response to vasopressin.
C. A decrease in urine output
RATIONALE: The major manifestations of diabetes insipidus are excessive urination and extreme thirst. Vasopressin is used to control frequent urination, increased thirst, and loss of water associated with diabetes insipidus. A decreased urine output is the desired response.
D. A decrease in specific gravity
RATIONALE: An increase in specific gravity (indicating a more concentrated urine) would be the desired response of vasopressin.
5. A nurse is reviewing the arterial blood gas (ABG) results of a client who the provider suspects has metabolic acidosis. Which of the following results should the nurse expect to see?

Detailed Answer Key
ATI Complex Endocrine Practice
A. pH below 7.35
RATIONALE: With acidosis, the pH is below 7.35. However, the pH alone does not indicate whether the problem is metabolic or respiratory. A pH above 7.45 indicates alkalosis.
B. HCO3 above 26 mEq/L
RATIONALE: With metabolic acidosis, the HCO3 is below 21 mEq/L.
C. PaO2 below 70 mm Hg
RATIONALE: With metabolic acidosis, the PaO2 is likely to be within the expected reference range of 80 to 100
mm Hg, unless the client has other complications that are causing hypoxia. D. PaCO2 above 45 mm Hg
RATIONALE: With metabolic acidosis, the PaCO2 is within the expected reference range of 35 to 45 mm Hg or below 35 mm Hg with respiratory compensation. An elevated PaCO2 indicates respiratory acidosis.
6. A nurse is caring for a client who is 8 hr postoperative following a subtotal thyroidectomy. In which of the following positions should the nurse keep the client?
A. High Fowler's with neck extended
RATIONALE: Neck extension could place excessive tension on the operative area and the sutures.
B. High Fowler's with neck in a neutral position.
RATIONALE: High Fowler's does not support the head and neck area well enough and could place excess pressure on the operative area.
C. Semi-Fowler's with neck extended
RATIONALE: Neck extension could place excessive tension on the operative area and the sutures. D. Semi-Fowler's with neck in a neutral position
RATIONALE: Semi-Fowler's is the most comfortable position for a client who has had thyroid surgery. Neck flexion could compromise the airway, and neck extension could place excessive tension on the operative area and the sutures. A neutral position is essential. [Show Less]
