A nurse is reviewing the medical history of a client who asks about the use of warfarin.
The nurse should identify which of the following findings as a contraindication for the administration of this medication?

Recent myocardial infarction.

Recent eye surgery.

Thrombophlebitis.

Breast cancer.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Recent myocardial infarction is not a contraindication for warfarin administration. Warfarin is often prescribed for patients with a history of myocardial infarction to prevent clot formation and reduce the risk of stroke.

Choice B rationale:

Recent eye surgery is a contraindication for the administration of warfarin. Warfarin can increase the risk of bleeding, which is particularly concerning after eye surgery due to the delicate nature of ocular tissues. Using anticoagulants in this scenario can lead to severe complications, including vision loss.

Choice C rationale:

Thrombophlebitis, inflammation of a vein with clot formation, is not a contraindication for warfarin administration. In fact, anticoagulants like warfarin are commonly prescribed to prevent the extension of clots and reduce the risk of complications associated with thrombophlebitis.

Choice D rationale:

Breast cancer is not a direct contraindication for warfarin administration. However, the decision to use anticoagulants in patients with a history of breast cancer should be made carefully, considering individual factors such as the stage of cancer, ongoing treatment, and overall risk of thromboembolic events.

Correct Answer is C

Explanation

The correct answer is choice C: Initiate continuous cardiac monitoring.

Choice A rationale:

Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by severe dehydration due to osmotic diuresis, and fluid replacement is a critical component of treatment to restore hydration and circulatory volume.

Choice B rationale:

Monitoring vital signs every 8 hours is not sufficient for a child with DKA. DKA is an acute, life-threatening condition that requires close monitoring of vital signs to detect changes in the patient’s condition promptly. Vital signs should be monitored more frequently, typically every 1 to 2 hours, depending on the severity of the DKA and institutional protocols.

Choice C rationale:

Continuous cardiac monitoring is recommended for a child with DKA. DKA can lead to serious electrolyte imbalances, such as hypokalemia, which can cause cardiac arrhythmias. Continuous cardiac monitoring allows for the early detection and treatment of these potential complications.

Choice D rationale:

Administering subcutaneous insulin 30 minutes before meals is not appropriate for the acute management of DKA. In DKA, insulin is typically administered intravenously to rapidly decrease blood glucose levels and correct metabolic acidosis. Subcutaneous insulin is not used until the patient is stable and able to eat.

A. Lift the penis so that it is perpendicular to the client's body. B. Cleanse the tip of the penis in a side-to-side motion. C. Pick up the catheter 13 cm (5 in) from its tip. D. Inflate the catheter balloon before insertion.

Correct Answer is A

Explanation

The correct answer is choiceA. Lift the penis so that it is perpendicular to the client’s body.

Choice A rationale:

Lifting the penis so that it is perpendicular to the client’s body straightens the urethra, making it easier to insert the catheter without causing trauma.

Choice B rationale:

While cleansing the tip of the penis in a circular motion is important for maintaining aseptic technique, it is not the specific action that facilitates the insertion of the catheter.

Choice C rationale:

Picking up the catheter 13 cm (5 in) from its tip is not a standard practice.The nurse should hold the catheter closer to the tip to maintain control and ensure accurate insertion.

Choice D rationale:

Inflating the catheter balloon before insertion can cause trauma to the urethra and is not recommended.The balloon should only be inflated once the catheter is correctly positioned in the bladder.
