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

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. When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient's blood pressure?

Correct answer: A

Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.

3. Which of the following vital signs can be expected in a child that is afebrile?

Correct answer: C

Rationale: The correct answer is the axillary temperature of 98.6 degrees F. Afebrile means without a fever, and an axillary temperature, which is taken in the armpit, is considered normal at 98.6 degrees F. Choice A is incorrect as a rectal temperature of 100.9 degrees F indicates a fever. Choice B is incorrect as an oral temperature of 38 degrees C is also indicative of a fever. Choice D is incorrect as not all options are wrong; only choices A and B are incorrect for an afebrile child.

4. You are taking care of 5 patients today. One of your patients wants water; another needs help walking to the bathroom; another just stated that they have chest pain; and another is crying because his daughter did not visit him today. Which patient care problem must you deal with first?

Correct answer: C

Rationale: The chest pain must be addressed immediately as it could indicate a serious condition like a heart attack. Treating chest pain is a top priority in healthcare settings due to the potential life-threatening nature of the symptom. Providing immediate attention to chest pain ensures prompt assessment, diagnosis, and intervention, which are crucial for patient safety and well-being. Addressing the other needs, such as providing water, assisting with bathroom needs, or emotional support, can follow once the urgent issue of chest pain has been managed. While the other patient concerns are important, the critical nature of chest pain requires immediate action to rule out severe cardiac events and provide appropriate care.

5. The nurse is preparing to assess a hospitalized patient who is experiencing significant shortness of breath. How should the nurse proceed with the assessment?

Correct answer: D

Rationale: When assessing a patient experiencing significant shortness of breath, it is crucial to prioritize the evaluation of areas directly related to the problem. Having the patient lie down may exacerbate the breathing difficulty. Therefore, the nurse should focus on examining the body areas pertinent to the issue, such as the respiratory and cardiac systems. Completing the rest of the assessment can be deferred until after addressing the immediate problem. Obtaining a complete history or involving family members should come after addressing the acute issue to ensure the patient's safety and comfort.
