1. During auscultation of a patient's heart sounds, the nurse hears an unfamiliar sound. Which action would the nurse take?

A. Ask the patient how he or she is feeling.
B. Document the findings in the patient's record.
C. Wait 10 minutes and auscultate the sound again.
D. Ask another nurse to double-check the finding.

Correct answer: D

Rationale: When encountering an unfamiliar sound during auscultation, it is crucial for the nurse to seek confirmation from another healthcare professional. Asking the patient about their feelings may not provide insight into the unfamiliar sound. Simply documenting the findings without verification may lead to errors in interpretation. Waiting and auscultating again after 10 minutes might delay necessary intervention. Consulting another nurse for a second opinion ensures accurate identification of the unfamiliar sound and appropriate follow-up actions.

2. Which of the following descriptions best describes the function of the thyroid gland?

A. The thyroid gland converts glucose into glycogen
B. The thyroid gland secretes cortisol during times of stress
C. The thyroid gland regulates body metabolism
D. The thyroid gland affects skin pigmentation

Correct answer: C

Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.

3. What does preload refer to?

A. The volume of blood entering the left side of the heart
B. The volume of blood entering the right side of the heart
C. The pressure in the venous system that the heart must overcome to pump the blood
D. The pressure in the arterial system that the heart must overcome to pump the blood

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

4. A urine pregnancy test:

A. May be negative even if a blood pregnancy test is positive.
B. Is positive only during the first trimester of pregnancy.
C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
D. All of the above.

Correct answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

5. The client starting an exercise program will progress to walking a 20-minute mile in one month.

A. Client will walk quickly three times a day
B. Client will be able to walk a mile
C. Client will have no alteration in breathing during the walk
D. Client will progress to walking a 20-minute mile in one month

Correct answer: D

Rationale: Outcome statements must be written in behavioral terms and identify specific, measurable client behaviors. They are stated in terms of the client with an action verb that, under identified conditions, will achieve the desired behavior. Choice A lacks specificity and does not mention a target time or goal. Choice B is vague and does not provide a specific target for improvement. Choice C focuses on a negative outcome (no alteration) rather than a positive goal. The correct answer, Choice D, is specific, measurable, and time-bound, making it a suitable outcome statement for a client starting an exercise program.
