Which technique will provide the most accurate measurement of the patient’s core temperature?

Axillary

Orally

Rectally

Forehead

Answer and Explanation

The Correct Answer is C

Choice A reason: This is an incorrect choice because the axillary method is not the most accurate measurement of the core temperature. The axillary method involves placing a thermometer under the patient's armpit and measuring the temperature of the skin surface. This method can be affected by factors such as sweating, clothing, and ambient temperature. The axillary method can underestimate the core temperature by 0.5°C to 1.5°C¹.

Choice B reason: This is an incorrect choice because the oral method is not the most accurate measurement of the core temperature. The oral method involves placing a thermometer in the patient's mouth and measuring the temperature of the sublingual pocket. This method can be affected by factors such as eating, drinking, smoking, and mouth breathing. The oral method can underestimate the core temperature by 0.3°C to 0.8°C¹.

Choice C reason: This is the correct choice because the rectal method is the most accurate measurement of the core temperature. The rectal method involves inserting a thermometer into the patient's rectum and measuring the temperature of the rectal mucosa. This method reflects the temperature of the blood flowing through the core of the body. The rectal method is considered the gold standard for measuring the core temperature¹.

Choice D reason: This is an incorrect choice because the forehead method is not the most accurate measurement of the core temperature. The forehead method involves placing a thermometer on the patient's forehead and measuring the temperature of the temporal artery. This method can be affected by factors such as sweating, hair, and ambient temperature. The forehead method can overestimate or underestimate the core temperature by 0.5°C to 1°C¹.

Correct Answer is B

Explanation

Choice A reason: This is incorrect. Presbyopia is not a term for age-related hearing loss. Presbyopia is a term for age-related vision loss. Presbyopia is a condition where the lens of the eye becomes less flexible and less able to focus on near objects. It can cause difficulty in reading, writing, or doing other close-up tasks.

Choice B reason: This is correct. Presbycusis is a term for age-related hearing loss. Presbycusis is a condition where the inner ear or the auditory nerve degenerates over time. It can cause difficulty in hearing high-pitched sounds, speech, or background noise. It can also affect the balance and the quality of life.

Choice C reason: This is incorrect. Meniere’s disease is not a term for age-related hearing loss. Meniere’s disease is a term for a disorder of the inner ear that causes episodes of vertigo, hearing loss, tinnitus, and ear fullness. It can affect people of any age, but it is more common in middle-aged adults. It can be triggered by stress, infection, or allergy.

Choice D reason: This is incorrect. Tinnitus is not a term for age-related hearing loss. Tinnitus is a term for a ringing, buzzing, or other sound in the ears or head that is not caused by an external source. It can affect people of any age, but it is more common in older adults. It can be caused by various factors, such as noise exposure, ear infection, medication, or hearing loss.

A. The patient frequently uses an alcohol-based sanitizer for hand hygiene. B. The patient takes acetaminophen 1000 mg every 4 hours around the clock. C. The patient takes alprazolam 0.25 mg every 8 hours. D. The patient rinses with a fluoride mouthwash after brushing the teeth.

Correct Answer is B

Explanation

Choice A reason: This is incorrect. The patient frequently using an alcohol-based sanitizer for hand hygiene does not pose a risk for poisoning. Alcohol-based sanitizers are safe and effective for reducing the transmission of germs.

Choice B reason: This is correct. The patient taking acetaminophen 1000 mg every 4 hours around the clock poses a risk for poisoning. Acetaminophen is a common over-the-counter pain reliever that can cause liver damage or failure if taken in excess or for a prolonged period of time. The maximum daily dose of acetaminophen for adults is 4000 mg.

Choice C reason: This is incorrect. The patient taking alprazolam 0.25 mg every 8 hours does not pose a risk for poisoning. Alprazolam is a prescription medication that belongs to the benzodiazepine class of drugs. It is used to treat anxiety and panic disorders. It can cause side effects such as drowsiness, dizziness, or dependence, but not poisoning.

Choice D reason: This is incorrect. The patient rinsing with a fluoride mouthwash after brushing the teeth does not pose a risk for poisoning. Fluoride is a mineral that helps prevent tooth decay and strengthen the enamel. It is added to many dental products and public water supplies. It can cause mild stomach upset if swallowed in large amounts, but not poisoning.
