1. The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?
- A. Slope of the earpieces should point forward toward the examiner's nose.
- B. It blocks out extraneous room noise but does not magnify sound.
- C. The tubing length should be 14 to 18 inches to prevent sound distortion.
- D. Both fit and quality of the stethoscope are important.
Correct answer: B
Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.
2. You see a sign over Mary Jones' bed when you arrive at 7 am to begin your day shift. The sign says, 'NPO'. Ms. Jones is on a regular diet. The patient asks for milk and some crackers. You _____________.
- A. can give her the milk but not the crackers
- B. can give her both the milk and the crackers
- C. can give her the crackers but not the milk
- D. cannot give her anything to eat or drink
Correct answer: D
Rationale: The correct answer is that you cannot give her anything to eat or drink. 'NPO' is the standard abbreviation for 'nothing by mouth,' indicating that the patient should not consume any food or liquids. It is crucial to adhere to this restriction to prevent any potential harm or complications in the patient's condition. Choices A, B, and C are incorrect because 'NPO' clearly specifies that the patient should not have anything to eat or drink, including milk and crackers. Providing these items could lead to adverse effects, so it is essential to follow the 'NPO' directive strictly.
3. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?
- A. Yield a falsely low blood pressure
- B. Yield a falsely high blood pressure
- C. Be the same, regardless of cuff size
- D. Vary as a result of the technique of the person performing the assessment
Correct answer: B
Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
4. A physician asks you to place the patient with his dorsal side facing the exam table. Which of the following accurately describes how the patient is positioned?
- A. The patient is lying prone.
- B. The patient is lying supine.
- C. The patient is lying in the recovery position.
- D. The patient is lying on his stomach.
Correct answer: B
Rationale: When the physician asks for the patient to be placed with their dorsal side facing the exam table, it means the patient should be lying on their back. This position is known as the supine position, where the patient's back is on the table, facing up towards the ceiling. Choice A, 'The patient is lying prone,' is incorrect as the prone position is when the patient is lying face down. Choice C, 'The patient is lying in the recovery position,' is incorrect as the recovery position is a lateral position typically used in first aid. Choice D, 'The patient is lying on his stomach,' is incorrect as it describes the prone position, not the supine position as required in this scenario.
5. Which of the following bony landmarks is described as a large, blunt, irregularly shaped process found on the lateral aspect of the proximal femur?
- A. Tubercle
- B. Tuberosity
- C. Condyle
- D. Trochanter
Correct answer: D
Rationale: The correct answer is D: Trochanter. The Greater Trochanter is located on the lateral aspect of the proximal femur and is a large, blunt, irregularly shaped bony process. It serves as an important attachment site for many muscles of the legs, providing leverage and movement. Choice A, Tubercle, is a small rounded projection, usually for the attachment of a ligament or tendon. Choice B, Tuberosity, is a large rounded projection, also typically for muscle attachment. Choice C, Condyle, refers to a rounded articular surface at the end of a bone, usually involved in joints.
