1. Digestion, elimination, and ___________ are the three functions of the digestive system.

• A. constriction
• B. relaxation
• C. absorption
• D. peristalsis

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.

2. What action by the nurse is appropriate when examining a 16-year-old male teenager?

• A. Discuss health teaching with the teenager to promote wellness.
• B. Ask the parent to step out of the room during the history and physical examination to respect the teenager's privacy.
• C. Use age-appropriate communication when speaking to the teenager to ensure understanding.
• D. Provide feedback that his body is developing normally and discuss the wide variation among teenagers on the rate of growth and development.

Correct answer: D

Rationale: During the examination of a 16-year-old male teenager, it is essential to provide feedback that his body is developing normally and to discuss the wide variation among teenagers regarding growth and development. This reassures the teenager about his health status and addresses any concerns about physical development. It is important to recognize that adolescents are very conscious of their body image and often compare themselves to their peers, hence the need for such feedback. Asking the parent to step out of the room respects the teenager's privacy and promotes open communication between the nurse and the teenager. Using age-appropriate communication is crucial to ensure that the teenager understands the information provided. Asking the parent to stay in the room may not be ideal as it can inhibit open discussion, and talking to the teenager as if they were a younger child is inappropriate and may undermine their autonomy and understanding.

3. How does the procedure for taking a pulse rate on an infant differ from an adult?

• A. Pulse rates are taken on infants using a different method.
• B. The apical pulse method is used on infants.
• C. Pulse rates on infants are taken with a sphygmomanometer.
• D. Pulse rates on infants are taken apically in the third intercostal space.

Correct answer: B

Rationale: The correct answer is B: The apical pulse method is used on infants. This method involves placing a stethoscope in the fifth intercostal space, mid-clavicular line, and counting the beats for a full minute. It is a preferred method for infants due to their small size and the difficulty in palpating peripheral pulses accurately. Choices A, C, and D are incorrect. Choice A is incorrect as pulse rates are indeed taken on infants, albeit using a different method. Choice C is incorrect as a sphygmomanometer is typically used for measuring blood pressure, not pulse rates. Choice D is incorrect as pulse rates on infants are usually taken apically in the fifth intercostal space, not the third.

4. After instructing the client on crutch walking technique, the nurse should evaluate the client's understanding by using which of the following methods?

• A. Return demonstration
• B. Explanation
• C. Achievement of 90 on written test
• D. Have the client explain the procedure to the family

Correct answer: A

Rationale: After teaching the client on crutch walking technique, assessing the client's understanding is crucial. The most effective method to evaluate the client's comprehension of a hands-on skill like crutch walking technique is through a return demonstration. This allows the nurse to observe the client performing the technique, ensuring they have grasped the instructions correctly and can execute the skill safely. While providing an explanation can help clarify doubts, it may not confirm the client's ability to perform the skill. Achieving a high score on a written test assesses cognitive understanding but not necessarily the practical application of the skill. Having the client explain the procedure to the family does not directly assess their ability to perform the skill themselves; it tests their ability to communicate the information to others.

5. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
