1. A client with type 1 diabetes is admitted with diabetic ketoacidosis
(DKA). Which finding does the nurse expect?
A. Serum bicarbonate 28 mEq/L
B. Arterial pH 7.25
C. Serum glucose 120 mg/dL
D. Positive ketones in the urine
CORRECT ANSWER: B. Arterial pH 7.25
Rationale: DKA is characterized by hyperglycemia, ketosis, and
metabolic acidosis. An arterial pH below 7.30 indicates acidosis,
which is expected in DKA. Serum bicarbonate is typically low (not
elevated), glucose is significantly elevated (>250 mg/dL), and
ketones are present in both blood and urine. However, the arterial
pH of 7.25 is the classic finding that confirms the diagnosis of DKA.
2. Which intervention is the priority for a client in the emergency
department with suspected hyperglycemic hyperosmolar state
(HHS)?
,A. Administration of IV potassium
B. Administration of regular insulin via IV bolus
C. Fluid resuscitation with 0.9% normal saline
D. Administration of sodium bicarbonate
CORRECT ANSWER: C. Fluid resuscitation with 0.9% normal
saline
Rationale: The priority intervention for HHS is fluid resuscitation to
correct severe dehydration and hyperosmolarity. Patients with HHS
typically present with profound dehydration and require large
volumes of isotonic fluids. Insulin administration is important but
secondary to fluid replacement. Potassium replacement may be
needed after fluid resuscitation, and sodium bicarbonate is not
indicated in HHS.
3. A client post-thyroidectomy complains of tingling around the
mouth and muscle twitching. Which laboratory result is the priority
to check?
A. Serum potassium
B. Serum calcium
C. Serum sodium
D. Serum phosphorus
CORRECT ANSWER: B. Serum calcium
,Rationale: Tingling around the mouth (perioral paresthesia) and
muscle twitching are classic signs of hypocalcemia. During
thyroidectomy, the parathyroid glands may be inadvertently
removed or damaged, leading to decreased parathyroid hormone
production and subsequent hypocalcemia. The priority is to check
serum calcium levels.
4. A nurse is caring for a client with Addisonian crisis. Which
medication does the nurse anticipate administering?
A. Insulin glargine
B. Hydrocortisone IV push
C. Levothyroxine
D. Desmopressin
CORRECT ANSWER: B. Hydrocortisone IV push
Rationale: Addisonian crisis (acute adrenal insufficiency) requires
immediate administration of glucocorticoids, typically
hydrocortisone IV push. This condition is life-threatening and results
from inadequate cortisol production. Insulin is used for diabetes,
levothyroxine for hypothyroidism, and desmopressin for diabetes
insipidus.
5. A client with syndrome of inappropriate antidiuretic hormone
(SIADH) has a serum sodium of 120 mEq/L. Which nursing action
is appropriate?
A. Administer hypertonic saline rapidly
, B. Restrict free water intake
C. Encourage increased oral fluid intake
D. Administer IV normal saline
CORRECT ANSWER: B. Restrict free water intake
Rationale: In SIADH, excessive antidiuretic hormone causes
water retention and dilutional hyponatremia. Fluid restriction is
the primary intervention to correct hyponatremia. Hypertonic
saline is reserved for severe symptomatic hyponatremia and must
be administered cautiously. Encouraging fluids would worsen the
condition.
6. A diabetic patient is unconscious and clammy. The nurse is unable
to obtain a blood glucose reading. What should the nurse do first?
A. Administer insulin
B. Administer glucagon 1 mg IM
C. Start an IV fluid bolus
D. Call a code blue
CORRECT ANSWER: B. Administer glucagon 1 mg IM
Rationale: An unconscious, clammy diabetic patient is likely
experiencing severe hypoglycemia. When IV access is delayed or the
patient cannot swallow, glucagon 1 mg IM is the emergency
treatment. Glucagon mobilizes glucose stores from the liver. Insulin
