To decrease intraocular pressure following cataract surgery, the nurse should instruct the client to avoid:

Deep breathing.

Ambulation.

Coughing.

Lying supine.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Deep breathing doesn't significantly affect intraocular pressure. Techniques enhancing oxygen exchange are safe and recommended for general well-being during postoperative recovery periods.

Choice B rationale

Ambulation promotes circulation and is generally safe after surgery. Avoiding ambulation is unnecessary for maintaining intraocular pressure levels unless medically contraindicated.

Choice C rationale

Coughing increases intraocular pressure due to abrupt pressure changes within the chest cavity and ocular system. This should be avoided to prevent complications after cataract surgery.

Choice D rationale

Lying supine does not inherently increase intraocular pressure unless other factors like improper postoperative positioning are involved. Proper positioning is important but lying supine itself isn't contraindicated.

Correct Answer is C

Explanation

Choice A rationale

Monitoring frequency of urination indicates bladder involvement, often related to cystitis. However, it does not indicate ascending progression to the kidneys, which is more severe and requires additional symptoms.

Choice B rationale

Dysuria, or painful urination, typically signifies lower urinary tract infection rather than progression to upper urinary tract infection, such as pyelonephritis. It is not specific to kidney involvement.

Choice C rationale

Flank pain and fever are hallmark symptoms of pyelonephritis, indicating ascending progression of infection from the bladder to the kidneys. These symptoms signal systemic involvement and require immediate medical attention.

Choice D rationale

Pyuria and hematuria are signs of bladder infection but do not indicate progression to kidney infection. These are specific to inflammation or infection in the lower urinary tract.

A. Patient's heart rate is 62 and regular. B. Patient is able to lie flat without reporting difficulty breathing. C. Patient does not report dyspnea after climbing one flight of stairs. D. Patient has weight loss of 3 lbs (1.4 kg) over 2 weeks.

Correct Answer is A

Explanation

Choice A rationale

Metoprolol decreases cardiac workload by reducing heart rate and myocardial oxygen demand. A heart rate of 62 is within normal limits, demonstrating effective beta-blocker action and improved cardiac efficiency.

Choice B rationale

Lying flat without difficulty breathing reflects improved respiratory status, which is more related to pulmonary management, not directly indicative of reduced cardiac workload or beta-blocker efficacy.

Choice C rationale

Absence of dyspnea after climbing stairs suggests improved physical fitness but does not directly measure the cardiac effects of metoprolol, which targets heart rate reduction and myocardial oxygen use.

Choice D rationale

Weight loss is related to overall health improvement or dietary changes rather than specific effects of metoprolol, which primarily impacts heart rate and cardiac oxygen consumption.
