Question 1 of 5
In assessing the nature of the stool of a client who has cystic fibrosis, what would the nurse expect to see?
Correct Answer: B
Rationale: Clay-colored stools indicate dysfunction of the liver or biliary tract. In the early stages of cystic fibrosis, fat absorption is primarily affected resulting in fat, foul, frothy, bulky stools. Dark brown stools indicate normal passage through the colon. Blood-tinged stools indicate dysfunction of the gastrointestinal (GI) tract.
Question 2 of 5
The nurse is preparing to administer oral potassium chloride to an elderly client. Which action should the nurse take before administering the medication?
Correct Answer: D
Rationale: Potassium chloride can worsen renal function in elderly clients. Checking the creatinine level assesses kidney function to ensure safe administration. Glucose hypocalcemia and withholding food are not directly related to potassium administration.
Question 3 of 5
The school nurse is assessing an elementary student with hemophilia who fell during recess. Which symptoms indicate hemarthrosis?
Correct Answer: D
Rationale: Hemarthrosis in hemophilia involves bleeding into joints, causing stiffness, aching, and decreased movement due to joint swelling and pain.
Question 4 of 5
When a client is receiving vasoactive therapy IV, such as dopamine (Intropin), and extravasation occurs, the nurse should be prepared to administer which of the following medications directly into the site?
Correct Answer: A
Rationale: Phentolamine is given to counteract the-adrenergic effects that cause ischemia and necrosis of local tissue. Epinephrine is an endogenous catecholamine that produces vasoconstriction and increases heart rate and contractility. Phenylephrine causes constriction of arterioles of skin, mucous membranes, and viscera, which in turn can cause ischemia and necrosis. Sodium bicarbonate is an alkalinizing agent that is incompatible with dopamine.
Question 5 of 5
Diagnostic assessment findings for an infant with possible coarctation of the aorta would include:
Correct Answer: D
Rationale: S1 and S2 in an infant with coarctation of the aorta are usually normal. S3 and S4 do not exist with this diagnosis. Either no murmur will be heard or a systolic murmur from an associated cardiac defect will be heard along the left upper sternal border. A diastolic murmur is not associated with coarctation of the aorta. Pulse pressure differences of >20 mm Hg exist between the upper extremities and the lower extremities. It is important to evaluate the upper and lower extremities with the appropriate-sized cuffs. Femoral and pedal pulses will be diminished or absent in infants with coarctation of the aorta.
