1. The mitral valve is synonymous with the term:

A. Left ventricle
B. Right atrium
C. Bicuspid valve
D. Tricuspid valve

Correct answer: C

Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.

2. How many cc are there in 25 ounces?

A. 250
B. 500
C. 750
D. 1000

Correct answer: C

Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.

3. The nurse supervises unlicensed assistive personnel (UAP) who are providing care for a patient with right lower lobe pneumonia. The nurse should intervene if which action by UAP is observed?

A. UAP splint the patient's chest during coughing.
B. UAP assist the patient to ambulate to the bathroom.
C. UAP help the patient to a bedside chair for meals.
D. UAP lower the head of the patient's bed to 15 degrees.

Correct answer: D

Rationale: The correct action for the nurse to intervene in is when the UAP lowers the head of the patient's bed to 15 degrees. This position can decrease ventilation in a patient with pneumonia, potentially worsening their condition. Choices B and C involve assisting the patient with activities of daily living and promoting mobility, which are appropriate for the patient's care. Choice A, splinting the patient's chest during coughing, can help the patient manage coughing effectively, which is also appropriate for a patient with pneumonia.

4. What is the initial step to take when a patient passes out at the front desk?

A. Call 911.
B. Initiate CPR.
C. Shake the patient and ask if they are okay.
D. Check for a pulse.

Correct answer: C

Rationale: The correct initial step when a patient passes out at the front desk is to shake the patient gently and ask if they are okay. This step aims to assess the patient's level of responsiveness. Checking for a pulse or initiating CPR should only be done if the patient does not respond to being shaken. Calling 911 can be the next step after assessing the patient's immediate condition and providing necessary assistance.

5. 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.
