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 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.

Correct Answer is A
Explanation
Choice A rationale:
"Phobias are characterized by persistent and irrational fear" (Choice A) is an accurate statement. Phobias are defined by the presence of an intense and irrational fear of a specific object or situation. This fear is persistent and often leads to avoidance behaviors, which can significantly impact the individual's daily life.
Choice B rationale:
"Phobias can be caused by biological factors only" (Choice B) is an inaccurate statement. Phobias can have various causes, including both biological and psychological factors. While there may be genetic predispositions to certain phobias, psychological factors, such as traumatic experiences or learned behaviors, can also contribute to the development of phobias.
Choice C rationale:
"Phobias can be diagnosed based on physical symptoms" (Choice C) is an inaccurate statement. Phobias are typically diagnosed based on the individual's reported symptoms, such as intense fear and avoidance behaviors. There are no specific physical symptoms that directly indicate the presence of a phobia.
Choice D rationale:
"Phobias can be managed with medication alone" (Choice D) is an inaccurate statement. Medication alone is not considered the primary treatment for phobias. While medications like selective serotonin reuptake inhibitors (SSRIs) or benzodiazepines may be prescribed to alleviate anxiety symptoms, the most effective treatment for phobias is psychotherapy, particularly exposure therapy or cognitive-behavioral therapy. These therapies address the root causes of the phobia and help individuals learn to manage their fear.
