A nurse is caring for a client who is 6 hr postoperative following application of an external fixator for a tibial fracture. Which of the following actions should the nurse take?
Maintain the affected extremity in a dependent position.
Palpate the dorsalis pedis pulse.
Wrap sterile gauze on the sharp point of the pins.
Adjust the clamps on the fixator frame.
The Correct Answer is B
Palpating the dorsalis pedis pulse is an essential action to monitor for adequate circulation and perfusion in an extremity with an external fixator, which is a device that stabilizes and aligns fractured bones with metal pins and rods outside of the skin. The other options are incorrect because they could cause complications such as edema, infection, or malalignment.

Correct Answer is D
Explanation
Desmopressin is a synthetic form of antidiuretic hormone (ADH), which regulates water balance in the body. Diabetes insipidus is a condition caused by a deficiency or resistance to ADH, resulting in excessive urination and thirst. Desmopressin helps reduce urine output and prevent dehydration by mimicking the action of ADH on the kidneys. Lithium is a mood stabilizer that can cause nephrogenic diabetes insipidus by interfering with the response of the kidneys to ADH. Regular insulin is used to treat diabetes mellitus, not diabetes insipidus, as it lowers blood glucose levels by facilitating its uptake into cells.
Furosemide is a diuretic that increases urine output and can worsen dehydration in clients with diabetes insipidus.
Correct Answer is D
Explanation
A hacking cough, especially at night or when lying down, is a common manifestation of left-sided heart failure, as fluid accumulates in the lungs and causes pulmonary congestion and dyspnea. Neck-vein distention and ankle edema are more indicative of right-sided heart failure, as fluid backs up into the systemic circulation and causes peripheral edema and jugular venous pressure elevation. Anorexia may occur in either type of heart failure, but it is not specific to left-sided heart failure.
