A client arrives at a hurricane disaster medical area seeking treatment for diarrhea.
Which source of contamination should the nurse consider when interviewing the client about exposure?
Nosocomial transmission in the medical area.
Food contamination from flood waters.
Drinking water contaminated by sewage.
Close living quarters at evacuation centers.
The Correct Answer is C
Choice A rationale:
Nosocomial transmission in the medical area. Rationale: Nosocomial transmission refers to infections that are acquired in healthcare settings. While it's essential for healthcare professionals to be aware of this risk, the client's presentation of diarrhea in a hurricane disaster area is more likely due to environmental factors rather than hospital-acquired infection.
Choice B rationale:
Food contamination from floodwaters. Rationale: In the aftermath of a hurricane, floodwaters can carry contaminants and pathogens, leading to food contamination. This is a significant concern, and the nurse should educate the client about the potential risks associated with consuming food exposed to floodwaters. However, the primary source of contamination for diarrhea is typically waterborne pathogens, which is addressed in choice C.
Choice C rationale:
Drinking water contaminated by sewage. Rationale: During natural disasters like hurricanes, sewage systems can become compromised, leading to the contamination of drinking water sources. This contamination poses a significant risk for diarrheal illnesses, as sewage often contains harmful pathogens. Therefore, the nurse should consider this as the most probable source of the client's exposure.
Choice D rationale:
Close living quarters at evacuation centers. Rationale: Close living quarters in evacuation centers can contribute to the spread of infectious diseases, including diarrheal illnesses. However, in this scenario, the client's chief complaint is diarrhea, and the nurse should prioritize investigating potential sources of waterborne contamination, as this aligns more closely with the client's symptoms.

Correct Answer is B
Explanation
This is the correct answer because it is the best way to assess for signs of ototoxicity, which is a potential adverse effect of aminoglycosides. Ototoxicity is the damage or injury to the inner ear or auditory nerve caused by certain drugs or chemicals. It can result in hearing loss, tinnitus, vertigo, or balance problems. Aminoglycosides are a class of antibiotics that are effective against gram-negative bacteria, but they can also cause ototoxicity by interfering with the function of the hair cells in the cochlea. The practical nurse (PN) should monitor the client's hearing by asking about any changes in hearing acuity, ringing in the ears, or difficulty understanding speech. The PN should also perform a hearing test using a tuning fork or an audiometer if available. The PN should report any signs of ototoxicity to the health care provider and discontinue the aminoglycoside as ordered.
a) Check for changes in vision.
This is not the correct answer because it is not related to ototoxicity. Vision is the ability to see and perceive objects and colors using the eyes and the brain. Vision may be affected by various factors, such as age, genetics, eye diseases, injuries, infections, or medications. However, aminoglycosides do not cause vision problems or impairments. The PN should check for changes in vision in a client who is receiving other drugs that can cause ocular toxicity, such as ethambutol, chloroquine, or digoxin.
c) Observe the skin for a rash.
This is not the correct answer because it is not related to ototoxicity. A rash is a change in the color, texture, or appearance of the skin that may be caused by various factors, such as allergies, infections, inflammation, or medications. A rash may present as redness, itching, swelling, blisters, bumps, or scales.
Aminoglycosides can cause skin reactions such as rash or urticaria in some clients who are hypersensitive or allergic to them. The PN should observe the skin for a rash in a client who is receiving an aminoglycoside and report any signs of an allergic reaction to the health care provider. However, a rash is not a sign of ototoxicity.
d) Measure the urinary output.
This is not the correct answer because it is not related to ototoxicity. Urinary output is the amount of urine produced and excreted by the kidneys and bladder. It is an indicator of renal function and fluid balance. The normal range for urinary output is 0.5 to 1 mL/kg/hour for adults. Urinary output may be affected by various factors, such as fluid intake, dehydration, diuretics, kidney disease, or medications. Aminoglycosides can cause nephrotoxicity, which is another potential adverse effect of these drugs. Nephrotoxicity is the damage or injury to the kidneys caused by certain drugs or chemicals. It can impair the kidneys' ability to filter waste products from the blood, resulting in reduced urine production and oliguria. The PN should measure the urinary output in a client who is receiving an aminoglycoside and report any signs of nephrotoxicity to the health care provider. However, urinary output is not a sign of ototoxicity
Correct Answer is D
Explanation
This is the correct answer because BUN and creatinine are the most important laboratory values to monitor for nephrotoxicity, which is the damage or injury to the kidneys caused by certain drugs or chemicals.
Nephrotoxicity can impair the kidneys' ability to filter waste products from the blood, resulting in elevated levels of BUN and creatinine. The normal range for BUN is 7 to 20 mg/dL, and for creatinine is 0.6 to 1.2 mg/dL. The practical nurse (PN) should review these values before administering an antibiotic that can cause nephrotoxicity, such as aminoglycosides, cephalosporins, vancomycin, or sulfonamides. The PN should also monitor the client for signs and symptoms of nephrotoxicity, such as decreased urine output, edema, hypertension, fatigue, nausea, and confusion.
a) Serum calcium
This is not the correct answer because serum calcium is not directly related to nephrotoxicity. Serum calcium is the amount of calcium in the blood, which is important for bone health, muscle contraction, nerve function, and blood clotting. The normal range for serum calcium is 8.5 to 10.2 mg/dL. Serum calcium may be affected by kidney disease, but it is not a reliable indicator of nephrotoxicity.
b) Hemoglobin and hematocrit
This is not the correct answer because hemoglobin and hematocrit are not directly related to nephrotoxicity. Hemoglobin is the protein in red blood cells that carries oxygen, and hematocrit is the percentage of red blood cells in the blood. The normal range for hemoglobin is 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women, and for hematocrit is 38.8 to 50% for men and 34.9 to 44.5% for women.
Hemoglobin and hematocrit may be affected by kidney disease, but they are not reliable indicators of
nephrotoxicity.
c) White blood cell count (WBC)
This is not the correct answer because WBC is not directly related to nephrotoxicity. WBC is the number of white blood cells in the blood, which are part of the immune system and fight infections. The normal range for WBC is 4,500 to 10,000 cells per microliter of blood. WBC may be elevated in response to an infection or inflammation, but it is not a reliable indicator of nephrotoxicity.
