1. Which brain structure serves as the heat-regulating center?

• A. Hypothalamus
• B. Pituitary Gland
• C. Pons
• D. Medulla Oblongata

Correct answer: A

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.

2. During a general survey of a patient, which finding is considered normal?

• A. Body mass index (BMI) of 20.
• B. When standing, the patient's base is narrow.
• C. The patient appears older than their stated age.
• D. Arm span (fingertip to fingertip) is greater than the height.

Correct answer: A

Rationale: A body mass index (BMI) of 20 is considered normal as the range for a normal BMI is between 19-24. When standing, a patient's base should be wide for stability and proper weight distribution. An older appearance than the stated age may indicate a history of chronic illness or chronic alcoholism. In a general survey, the patient's arm span (fingertip to fingertip) should approximately equal the patient's height. An arm span greater than the height may suggest Marfan syndrome. Therefore, the correct choice is a normal BMI of 20, which falls within the healthy range. Choices B, C, and D all describe abnormal findings that may indicate underlying health conditions or syndromes.

3. A client is complaining of pain that starts in the shoulder and travels down the length of his arm. This type of pain is referred to as:

• A. Referred pain
• B. Superficial pain
• C. Radiating pain
• D. Precipitating pain

Correct answer: C

Rationale: Radiating pain is the correct term for pain that originates in one part of the body and extends to other related areas. In this scenario, the pain starting in the shoulder and traveling down the arm describes radiating pain. Referred pain (Choice A) is pain felt at a site different from the actual origin of the pain. Superficial pain (Choice B) is pain that arises from the skin or tissues just beneath it. Precipitating pain (Choice D) refers to pain that is triggered by specific actions or events, not the characteristic described in the question.

4. A 70-year-old man has a blood pressure of 150/90 mm Hg in a lying position, 130/80 mm Hg in a sitting position, and 100/60 mm Hg in a standing position. How should the nurse evaluate these findings?

• A. These readings are a normal response and attributable to changes in the patient's position.
• B. The change in blood pressure readings is called orthostatic hypotension.
• C. The blood pressure reading in the lying position is within normal limits.
• D. The change in blood pressure readings is considered within normal limits for the patient's age.

Correct answer: B

Rationale: The correct answer is, 'The change in blood pressure readings is called orthostatic hypotension.' Orthostatic hypotension is defined as a drop in systolic pressure of �20 mm Hg or �10 mm Hg drop in diastolic pressure that occurs with a quick change to a standing position. This condition is common in individuals on prolonged bed rest, older adults, those with hypovolemia, or taking specific medications. The blood pressure readings provided in the question (150/90 mm Hg lying, 130/80 mm Hg sitting, and 100/60 mm Hg standing) demonstrate a significant change in blood pressure with position changes, which is indicative of orthostatic hypotension. Choices A, C, and D are incorrect because the readings do not indicate a normal response or blood pressure within normal limits for the patient's age; rather, they suggest the presence of orthostatic hypotension.

5. Mrs. D is a pregnant client who is 33 weeks' gestation and is admitted for bright red vaginal bleeding. Her physician suspects placenta previa. All of the following nursing interventions are appropriate for this client except:

• A. Institute complete bed rest for the client
• B. Assess uterine tone to determine condition
• C. Perform a vaginal exam to assess cervical dilation
• D. Measure and record blood loss each shift

Correct answer: C

Rationale: A client with placenta previa has part of the placenta covering some or all of the cervical opening. Performing a vaginal exam for placenta previa may cause significant bleeding and should be avoided unless directed by a physician, and preparations are made for emergency delivery. **Choice A** is correct as complete bed rest is essential to decrease the risk of further bleeding. **Choice B** is appropriate as assessing uterine tone helps in determining the condition of the uterus and can provide important information for the healthcare team. **Choice D** is also a necessary intervention as monitoring and recording blood loss is crucial in assessing the client's condition and response to treatment.
