1. A home care nurse is instructing a client with hyperemesis gravidarum
about measures toease the nausea and vomiting. The nurse tells the
client to:
A. Eat foods high in calories and fat
B. Lie down for at least 20 minutes after meals
C. Eat carbohydrates such as cereals, rice, and pasta Correct
D. Consume primarily soups and liquids at mealtimes
,NURSING 240 ACTUAL EXAM STUDY GUIDE
Rationale: Low-fat foods and easily digested carbohydrates such as fruit, breads, cereals, rice, and
pasta provide important nutrients and help prevent a low blood glucose level, which can cause
nausea. Soups and other liquids should be taken between meals to avoid distending the stomach
and triggering nausea. Sitting upright after meals reduces gastric reflux. Additionally, food portions
should be small and foods with strong odors should be eliminated from the diet, because food smells
often incite nausea.
A nurse is caring for a client with preeclampsia who is receiving a magnesium
sulfate infusion toprevent eclampsia. Which finding indicates to the nurse that
the medication is effective?
E. Clonus is present. Incorrect
F. Magnesium level is 10 mg/dL.
G. Deep tendon reflexes are absent.
,NURSING 240 ACTUAL EXAM STUDY GUIDE
H. The client experiences diuresis within 24 to 48 hours. Correct
Rationale: Magnesium sulfate is effective in preventing seizures (eclampsia) if diuresis occurs within
24 to 48 hours of the start of the infusion. As part of the therapeutic response, renal perfusion is
increased and the client is free of visual disturbances, headache, epigastric pain, clonus (the rapid
rhythmic jerking motion of the foot that occurs when the client’s lower leg is supported and the foot is
sharply dorsiflexed), and seizure activity. Hyperreflexia indicates cerebral irritability. Clonus is
normally not present. The therapeutic magnesium level is 4 to 8 mg/dL. Reflexes range from 1+ to
2+ but should not be absent.
A client with preeclampsia who is receiving magnesium sulfate in an intravenous
infusion exhibitssigns of magnesium toxicity. The nurse immediately prepares
for the administration of:
I. Vitamin K
J. Protamine sulfate Incorrect
K. Calcium gluconate Correct
L. Naloxone hydrochloride
Rationale: Calcium gluconate is the antidote to magnesium sulfate because it antagonizes the
effects of magnesium at the neuromuscular junction. It should be readily available whenever
magnesium is administered. Vitamin K is the antidote in cases of hemorrhage induced by the
administration of oral anticoagulants such as warfarin sodium (Coumadin). Protamine sulfate is the
, NURSING 240 ACTUAL EXAM STUDY GUIDE
antidote in cases of hemorrhage induced by the administration of heparin. Naloxone hydrochloride is
administered to treat opioid-induced respiratory depression.
A nurse instructs a pregnant client about foods that are high in folic acid. Which
item does the nursetell the client is the best source of folic acid?
M. Milk
N. Steak
O. Chicken
P. Lima beans Correct
Rationale: The best sources of folic acid are liver; kidney, pinto, lima, and black beans; and fresh
dark-green leafy vegetables. Other good sources of folic acid are orange juice, peanuts, refried
beans, and peas. Milk is high in calcium. Chicken and steak are high in protein.
A nurse is providing instructions to a mother of an infant with seborrheic
dermatitis (cradle cap)about treatment of the condition. The nurse tells the
mother to:
Q. Avoid the use of shampoo on the infant’s scalp Incorrect
R. Apply oil to the affected area on the infant’s scalp Correct
S. Wash the infant’s scalp daily, using only tepid water
T. Shampoo the infant’s scalp, avoiding the anterior fontanel area
