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.

When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?
- A. Asian
- B. Hispanic
- C. American Indian
- D. African American/Black
Correct Answer: B
Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.
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.
The healthcare provider is preparing to perform a physical assessment. Which statement is true about the inspection phase of the physical assessment?
- A. Usually yields little information
- B. Takes time and reveals a surprising amount of information
- C. May be somewhat uncomfortable for the expert practitioner
- D. Requires a thorough examination of the patient's body before proceeding with palpation
Correct Answer: B
Rationale: During the inspection phase of a physical assessment, it is essential to take time as it can reveal a significant amount of information. Initially, it may feel uncomfortable for the examiner to focus solely on observing the patient without immediate action. Rushing through inspection is not recommended as it can lead to missing important cues. Train yourself to be thorough during inspection by observing carefully and taking the time needed to gather essential data. Choices A, C, and D are incorrect because inspection typically provides valuable information, may feel uncomfortable at first but is necessary for a comprehensive assessment, and does not involve a quick glance but requires a focused and detailed observation.
The nurse is preparing to perform a physical assessment. The correct action by the nurse is reflected by which statement?
- A. Performs the examination from both sides of the bed.
- B. Examines tender or painful areas last to help relieve the patient's anxiety.
- C. Follows a flexible examination sequence, considering the patient's age and condition.
- D. Organizes the assessment to ensure that the patient does not change positions too often.
Correct Answer: D
Rationale: The nurse should organize the assessment to minimize the patient's need to change positions frequently, ensuring efficiency and comfort. It is essential to perform the examination from both sides of the bed to facilitate a comprehensive assessment. Examining tender or painful areas last can help reduce patient discomfort and anxiety. The examination sequence should be flexible, taking into account the patient's age, condition, and specific needs. This approach allows for a tailored and patient-centered assessment, optimizing the quality of care provided.
When performing a physical assessment, what technique should the nurse always perform first?
- A. Palpation
- B. Inspection
- C. Percussion
- D. Auscultation
Correct Answer: B
Rationale: During a physical assessment, the nurse should always begin with inspection. The sequence of techniques for physical examination is inspection, palpation, percussion, and auscultation. These skills are performed in a specific order, except for the abdominal assessment where auscultation precedes palpation and percussion. Inspection allows the nurse to observe and gather initial information without direct contact. It is a crucial step that provides valuable insights before proceeding to palpation, percussion, and auscultation. Therefore, choice B, 'Inspection,' is the correct answer. Choices A, C, and D are incorrect because they should follow inspection in the sequence of a comprehensive physical assessment.
