What is the flap of tissue that covers the trachea upon swallowing called?
- A. Epidermis
- B. Endocardium
- C. Epiglottis
- D. Epistaxis
Correct Answer: C
Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.

What does the medical term 'basophilia' refer to?
- A. An attachment of the epithelial cells of the skin to a basement membrane
- B. An overabundance of a particular white blood cell in the peripheral blood
- C. An underrepresentation of basophils on a blood smear
- D. None of the above
Correct Answer: B
Rationale: The correct answer is 'An overabundance of a particular white blood cell in the peripheral blood.' Basophilia specifically indicates an increased number of basophils in the peripheral blood. It can be observed in conditions like leukemia and certain allergic reactions. Choice A is incorrect as it describes something unrelated to basophilia. Choice C is incorrect as it suggests a decrease in basophils, which is opposite to the actual meaning of basophilia. Choice D is also incorrect as basophilia does have a defined medical significance.
How does the procedure for taking a pulse rate on an infant differ from an adult?
- A. Pulse rates are taken on infants using a different method.
- B. The apical pulse method is used on infants.
- C. Pulse rates on infants are taken with a sphygmomanometer.
- D. Pulse rates on infants are taken apically in the third intercostal space.
Correct Answer: B
Rationale: The correct answer is B: The apical pulse method is used on infants. This method involves placing a stethoscope in the fifth intercostal space, mid-clavicular line, and counting the beats for a full minute. It is a preferred method for infants due to their small size and the difficulty in palpating peripheral pulses accurately. Choices A, C, and D are incorrect. Choice A is incorrect as pulse rates are indeed taken on infants, albeit using a different method. Choice C is incorrect as a sphygmomanometer is typically used for measuring blood pressure, not pulse rates. Choice D is incorrect as pulse rates on infants are usually taken apically in the fifth intercostal space, not the third.
Following hospitalization for congestive heart failure, a client is discharged. The nurse teaching the family suggests they encourage the client to rest frequently in which of the following positions?
- A. High Fowler's
- B. Supine
- C. Left lateral
- D. Low Fowler's
Correct Answer: A
Rationale: The correct answer is High Fowler's. Sitting in a chair or resting in a bed in the high Fowler's position helps decrease the cardiac workload and facilitates breathing in clients with congestive heart failure. This position helps reduce venous return and increases lung expansion, improving oxygenation. The supine position (choice B) may lead to increased pressure on the heart and lungs, making it less suitable for these clients. The left lateral position (choice C) is not as effective as High Fowler's in reducing cardiac workload and improving breathing. Low Fowler's position (choice D) does not provide the same benefits as the High Fowler's position for clients with congestive heart failure.
The abbreviation pc is defined as ________________.
- A. before the meal
- B. with the meal
- C. after the meal
- D. post corpi
Correct Answer: C
Rationale: The correct answer is C: 'after the meal.' In medical terminology, 'pc' is an abbreviation for 'post cibum,' which means 'after eating' or 'after the meal.' This term is used to indicate when a medication should be taken concerning meals. Choices A, B, and D are incorrect. 'Before the meal' (A) is typically abbreviated as 'ac,' 'with the meal' (B) is abbreviated as 'pc,' and 'post corpi' (D) is not a valid medical abbreviation or term.
A physician's order instructs a nurse to take a temperature at the axilla. Where would the nurse place the thermometer?
- A. In the rectum
- B. In the mouth
- C. On the temples
- D. In the armpit
Correct Answer: A
Rationale: When a physician's order specifies taking a temperature at the axilla, the nurse should place the thermometer in the armpit. The axilla is the anatomical area of the armpit located under the arms, proximal to the trunk. Placing the thermometer in the rectum (Choice A) is used for rectal temperature measurements, in the mouth (Choice B) for oral temperature measurements, and on the temples (Choice C) is not a common site for temperature assessment. Therefore, the correct placement based on the given instruction is in the armpit.
