Question 1 of 5
A client is admitted to the labor and delivery unit in active labor. The physician performs an amniotomy. Which observation would the nurse expect to make immediately after the amniotomy?
Correct Answer: C
Rationale: After an amniotomy the nurse expects to observe a large amount of clear or straw-colored amniotic fluid indicating normal amniotic fluid. Fetal heart tones of 160 bpm are normal but not specific to amniotomy contractions are unrelated and green fluid suggests meconium which is abnormal.
Question 2 of 5
The nurse is teaching a client with a history of osteoporosis about dietary modifications. The nurse should tell the client to increase intake of:
Correct Answer: A
Rationale: Calcium-rich foods strengthen bones and help prevent further bone loss in osteoporosis, a critical dietary modification.
Question 3 of 5
Stat serum electrolytes ordered for a client in acute renal failure revealed a serum potassium level of 6.4. The physician is immediately notified and orders 50 mL of dextrose and 10 U of regular insulin IV push. The nurse administering these drugs knows the rationale for this therapy is to:
Correct Answer: D
Rationale: Sodium polystyrene sulfonate (Kayexalate), a cation exchange resin, exchanges sodium ions for potassium ions in the large intestine reducing the serum potassium. Calcium is administered to protect the myocardium from the adverse effects of hyperkalemia. Serum levels reflect hyperkalemia. Rapid catabolism releases potassium from the body tissue into the bloodstream. Infection and hyperthermia increase the process of catabolism. The administration of dextrose and regular insulin IV forces potassium back into the cells decreasing the potassium in the serum.
Question 4 of 5
An expected response to sodium polystyrene sulfonate (Kayexalate) is:
Correct Answer: A
Rationale: Whole blood is the transfusion component of choice when large volumes of blood need to be replaced. Whole blood contains all blood components that are lost during active bleeding.
Question 5 of 5
A 67-year-old man had a physical examination prior to beginning volunteer work at the hospital. A routine chest x-ray demonstrated left ventricular hypertrophy. His blood pressure was 180/110. He is 45 lb overweight. His diet is high in sodium and fat. He has a strong family history of hypertension. The client is placed on antihypertensive medication; a low-sodium, low-fat diet; and an exercise regimen. On his next visit, compliance would best be determined by:
Correct Answer: A
Rationale: A blood pressure within acceptable range best demonstrates compliance, but weight loss cannot be accomplished without adherence to medication, diet, and exercise. Absence of side effects does not indicate compliance with medication. Pill counts can be misleading because the client can alter pill counts prior to visit. Left ventricular hypertrophy is not an accurate measure of compliance because hypertrophy frequently does not decrease even with pharmacological management. Therapeutic blood levels measure the drug level at the time of the test. There is no indication of compliance several days before testing.
