The patient is standing 10 feet from the eye chart but can only read what a person with normal vision could see from 200 feet away. What does the nurse document about the patient's vision?

20/200

200/10

10/200

200/20

Answer and Explanation

The Correct Answer is A

Visual acuity is measured using the Snellen chart, which compares the distance at which a patient can read letters to the standard distance a person with normal vision can read the same letters. It reflects the clarity and resolving power of the retina and central visual pathways.

Rationale:

A. 20/200 indicates the patient can read at 20 feet what a person with normal vision can read at 200 feet. This represents severe visual impairment consistent with significant reduction in visual acuity. The ratio is standardized with 20 feet as the testing distance.

B. 200/10 reverses the standard Snellen notation format. Visual acuity is always expressed with the testing distance (20 feet) as the numerator. This option is not clinically valid and does not represent correct ophthalmologic documentation.

C. 10/200 incorrectly uses 10 feet as the testing distance, which is not standard for Snellen chart interpretation. It does not reflect the correct ratio definition and therefore is not an accepted visual acuity measurement format.

D. 200/20 incorrectly reverses numerator and denominator values. This would imply abnormal scaling opposite of Snellen convention. It does not represent proper documentation of visual acuity and is not clinically interpretable.

Correct Answer is ["C","D","E"]

Explanation

Sexually transmitted infections involve pathogen transmission through mucosal exposure, requiring antimicrobial therapy and partner management. Effective control includes barrier protection and simultaneous treatment to prevent reinfection, complications such as pelvic inflammatory disease, and ongoing community transmission.

Rationale:

A. Intrauterine devices provide contraception but do not protect against STI transmission. In active infection, insertion may increase risk of ascending infection. Lack of barrier protection and potential for infection spread make this inappropriate.

B. Frequent douching disrupts protective vaginal flora and alters pH, increasing susceptibility to infections and facilitating pathogen ascent. It does not treat or prevent STIs. Presence of flora disruption and increased infection risk makes this harmful.

C. Condom use provides a physical barrier that reduces exposure to infected secretions during sexual activity. It significantly lowers transmission risk. Presence of barrier protection and decreased pathogen exposure makes this a key intervention.

D. Treating the patient with appropriate antimicrobial therapy eradicates the causative organism and prevents progression and complications. Prompt therapy is essential. Presence of targeted treatment and prevention of disease progression supports this.

E. Treating sexual partners prevents reinfection and interrupts transmission cycles within the population. Untreated partners act as reservoirs. Presence of partner therapy and reduction of reinfection risk makes this necessary.

A. A 55-year-old patient with an acute kidney injury (AKI) whose morning potassium level is 5.1 (normal 3.5-5.0) and who is waiting for the stat dose of sodium polystyrene sulfonate (Kayexalate) to be delivered from the pharmacy. B. A 72-year-old patient 4 hours post-percutaneous coronary intervention (PCI) with a non-bleeding groin puncture site and a reported dull, constant backache rated 4/10. C. A 45-year-old patient with a history of seizures who missed the 0600 dose of phenytoin (Dilantin) because it was held for a critically low albumin level. D. A 60-year-old patient with chronic obstructive pulmonary disease (COPD) and a tracheostomy whose heart rate is 105/min (baseline 88/min) and whose family member reports a sudden increase in noisy respirations.

Correct Answer is D

Explanation

Priority-setting in acute care follows the ABCs framework (airway, breathing, circulation) and focuses on immediate threats to oxygenation and ventilation. Patients with respiratory compromise, especially those with COPD and artificial airways, are at high risk for rapid deterioration due to airway obstruction, secretion retention, and impaired gas exchange.

Rationale:

A. 5.1 mmol/L is only mildly elevated and does not indicate immediate life-threatening hyperkalemia. The patient is stable while awaiting sodium polystyrene sulfonate. No ECG changes or severe electrolyte imbalance are described, so this is not the first priority.

B. Post-PCI patients require monitoring for complications such as bleeding or retroperitoneal hemorrhage. However, a stable groin site and mild backache rated 4/10 suggest no immediate hemodynamic instability. This finding warrants assessment but is not the highest priority.

C. Missed phenytoin dose due to low albumin is important but not immediately life-threatening. While seizure risk may increase, there is no active seizure or neurologic deterioration described. This represents a medication management issue rather than an acute emergency.

D. A COPD patient with a tracheostomy and sudden increase in noisy respirations indicates possible airway obstruction from mucus plugging or secretion buildup. The elevated heart rate suggests early respiratory distress and hypoxemia. This is an immediate airway emergency requiring urgent assessment.
