Extract:
Question 1 of 5
Which electrolyte will be high in a client with hypoparathyroidism?
Correct Answer: A
Rationale: Hypoparathyroidism reduces PTH, raising phosphorus by decreasing excretion. Calcium drops, magnesium and potassium are unaffected.
Question 2 of 5
A nurse is assessing a client who has myxedema. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Myxedema, severe hypothyroidism, causes fluid retention and glycosaminoglycan deposits, leading to non-pitting leg edema. Heat intolerance and tachycardia occur in hyperthyroidism, while diarrhea is linked to increased gut motility, not myxedema's constipation.
Question 3 of 5
The nurse is educating a client about Parkinson's disease. Which of the following statements would require further teaching?
Correct Answer: D
Rationale: Parkinson's results from dopamine deficiency, not acetylcholine. Soft foods , prune juice , and carbidopa-levodopa are correct management strategies.
Question 4 of 5
A nurse is preparing to administer levothyroxine 100 mcg PO daily. Available is levothyroxine 50 mcg tablets. How many tablets should the nurse administer daily? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: 2 tablets (50 mcg each) equal 100 mcg, the prescribed dose. 1 tablet underdoses, 3 or 4 tablets overdose, risking hyperthyroidism.
Question 5 of 5
A nurse is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the nurse anticipate administering?
Correct Answer: B
Rationale: Heparin prevents clot growth in pulmonary embolism, stabilizing it. Dexamethasone reduces inflammation, atropine treats bradycardia, and furosemide manages fluid, not clots.
