Nursing Elites

1. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

2. What health concerns should Nurse Oliver expect a client with hypothyroidism to report?

• A. Increased appetite and weight loss
• B. Puffiness of the face and hands
• C. Nervousness and tremors
• D. Thyroid gland swelling

Correct answer: B

Rationale: Puffiness of the face and hands is a classic symptom of hypothyroidism. This occurs due to fluid retention and is commonly observed in individuals with an underactive thyroid gland. Increased appetite and weight loss (Choice A) are more indicative of hyperthyroidism, where there is an overproduction of thyroid hormones leading to increased metabolism. Nervousness and tremors (Choice C) are associated with hyperthyroidism, not hypothyroidism. Thyroid gland swelling (Choice D) typically indicates goiter, which can be present in both hyperthyroidism and hypothyroidism but is not a specific symptom that clients with hypothyroidism commonly report.

3. During the physical examination, Nurse Noah expects to assess which sign in a female client with a serum calcium level of 7.2 mg/dl?

• A. Trousseau's sign
• B. Homans' sign
• C. Hegar's sign
• D. Goodell's sign

Correct answer: A

Rationale: Trousseau's sign is a clinical indicator of hypocalcemia, characterized by carpal spasm when a blood pressure cuff is inflated above systolic pressure and maintained for a few minutes. This occurs due to increased neuromuscular irritability associated with low serum calcium levels. Homans' sign is used to assess for deep vein thrombosis and involves calf pain upon dorsiflexion of the foot. Hegar's sign is a softening of the lower uterine segment seen in pregnancy, while Goodell's sign is softening of the cervix also seen in pregnancy. Therefore, in this scenario, the correct assessment related to hypocalcemia would be Trousseau's sign.

4. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

Correct answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.

5. Which outcome indicates that treatment of a male client with diabetes insipidus has been effective?

• A. Fluid intake is less than 2,500 ml/day
• B. Urine output measures more than 200 ml/hour
• C. Blood pressure is 90/50 mm Hg
• D. The heart rate is 126 beats/minute

Correct answer: A

Rationale: The correct outcome indicating effective treatment of diabetes insipidus in a male client is a fluid intake of less than 2,500 ml/day. In diabetes insipidus, excessive urination causes increased fluid intake to compensate for the fluid loss. By effectively managing the condition, the client's fluid intake should decrease. Choices B, C, and D do not directly reflect the effectiveness of treatment for diabetes insipidus. Increased urine output (choice B) may indicate inadequate control of the condition, while low blood pressure (choice C) and a high heart rate (choice D) are not specific indicators of effective treatment for diabetes insipidus.
