1. A patient with hyperthyroidism is most likely to present with which of the
following clinical manifestations?
A) Cold intolerance, weight gain, bradycardia
B) Heat intolerance, tachycardia, weight loss
C) Constipation, dry skin, hypotension
D) Lethargy, bradycardia, weight gain
Answer: B
Rationale: Hyperthyroidism results from excessive thyroid hormone
production, which increases metabolic rate. Classic symptoms include heat
intolerance (increased heat production), tachycardia (increased sympathetic
response), and weight loss (increased metabolism). Causes include Graves'
disease and thyroiditis. Treatment options include PTU, Methimazole,
radioactive iodine therapy, or thyroidectomy.
2. A nurse is caring for a patient who just underwent a thyroidectomy. Which
of the following items should be kept at the bedside as a priority?
A) Insulin syringe and glucose gel
B) Tracheostomy tray and calcium gluconate
C) Potassium chloride IV and cardiac monitor
D) Blood pressure cuff and oxygen mask
Answer: B
Rationale: Post-thyroidectomy complications include: (1) respiratory
obstruction from laryngeal spasms or stridor requiring a tracheostomy tray,
and (2) hypocalcemia if parathyroid glands were inadvertently removed. Signs
of hypocalcemia include Chvostek's and Trousseau's signs. Calcium gluconate
must be immediately available for IV administration.

3. A patient presents with fever of 1 degree elevation, tachycardia, and
systolic hypertension after thyroid surgery. The nurse recognizes these as
signs of:
A) Thyroid storm
B) Myxedema coma
C) Hypocalcemic crisis
D) Serotonin syndrome
Answer: A
Rationale:Thyroid storm is a life-threatening emergency characterized by
fever (even 1 degree elevation is an emergency), tachycardia, and systolic
hypertension. Treatment includes PTU and Methimazole (to block hormone
synthesis), hydrocortisone, prednisone, and cooling blankets. This is a medical
emergency requiring immediate intervention.
4. A patient with hypothyroidism is prescribed levothyroxine (Synthroid).
Which instruction should the nurse include in patient teaching?
A) Take with breakfast to prevent GI upset
B) Take in the morning, 30 minutes before meals
C) Take with fiber supplements for better absorption
D) Take at bedtime to reduce daytime side effects
Answer: B
Rationale: Levothyroxine should be taken in the morning on an empty
stomach, 30 minutes before meals for optimal absorption. The medication
should be started at a low dose and increased slowly ("go low and slow") to
prevent cardiac complications. Fiber supplements should not be taken with
levothyroxine as they decrease absorption. Monitor for chest pain indicating
possible cardiac stress.

5. Which of the following is the priority intervention for a patient experiencing
myxedema coma?
A) Administer oral levothyroxine immediately
B) Apply warm blankets and prepare for mechanical ventilation
C) Restrict fluids and administer diuretics
D) Administer insulin and monitor blood glucose
Answer: B
Rationale: Myxedema coma is a severe hypothyroid state with hypothermia,
hypotension, and high morbidity. Causes include stopping levothyroxine,
surgery, chemo, or acute illness. Priority treatment includes mechanical
ventilation support, warm blankets for hypothermia, IV levothyroxine, and IV
glucose. This is a medical emergency.
6. A patient with hyperparathyroidism is at risk for which electrolyte
imbalance?
A) Hypocalcemia
B) Hypercalcemia
C) Hyperkalemia
D) HyponatremiaAnswer: B
Rationale:* Hyperparathyroidism causes excessive PTH secretion, leading to
hypercalcemia as calcium is released from bones and absorbed from the GI
tract. Causes include adenoma, hyperplasia, or cancerous tumor (primary) or
severe calcium deficit, vitamin D deficiency, or chronic kidney failure
(secondary). Symptoms include hypercalcemia, epigastric pain, and bone
weakness. Treatment includes diuretics, hydration (NS, Furosemide,
Bumetanide), calcitonin, and oral phosphate.
