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

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.

2. You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?

Correct answer: B

Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.

3. As a valued member of the team on your nursing care unit, you are trying to determine whether the team is doing well. Which of the following is a sign that your team is successful?

Correct answer: A

Rationale: One of the key indicators of a successful team is the ability to handle conflict positively. Conflict, when managed well, can lead to team growth and development. Choice B is incorrect because suppressing negative feelings does not indicate team success; open communication is crucial. Choice C is incorrect as successful teams view mistakes as learning opportunities rather than resorting to disciplinary action. Choice D is incorrect because successful teams are often innovative and willing to take risks rather than maintaining the status quo.

4. Which contraindication should be assessed for prior to administering an immunization to a child?

Correct answer: C

Rationale: Before administering immunizations to children, it is crucial to assess for contraindications. A depressed immune system, such as that seen in conditions like HIV or due to chemotherapy, is a significant contraindication. Immunizations may not be safe or effective in children with compromised immune systems. Mild cold symptoms, although not ideal, are not a contraindication for routine immunizations. Chronic asthma, while a consideration, is not a direct contraindication for routine immunizations. Allergy to eggs is a contraindication for specific vaccines, such as influenza vaccine that is grown in eggs, but it is not a contraindication for all immunizations.

5. A 2-year-old child has been brought to the clinic for a well-child checkup. What is the best way for the nurse to begin the assessment?

Correct answer: C

Rationale: The best place to examine the toddler is on the parent's lap. Toddlers understand symbols; therefore, a security object is helpful. Initially, the focus is more on the parent, which allows the child to adjust gradually and to become familiar with you. A 2-year-old child does not like to take off his or her clothes. Therefore, ask the parent to undress one body part at a time.
