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.

Efforts by healthcare facilities to reduce the incidence of hospital-acquired infections (HAIs) include an awareness of which of the following?
- A. The CDC requires all states to report HAI rates from each hospital.
- B. Ensure that the restraints are tied to the side rails.
- C. The gastrointestinal tract is a common site for HAIs.
- D. Joint Commission considers death or serious injury from HAIs a sentinel event.
Correct Answer: D
Rationale: Efforts to reduce hospital-acquired infections (HAIs) involve being aware that the Joint Commission considers death or serious injury resulting from HAIs a sentinel event, which must be reported. While more than 20 states require reporting of HAI rates to the CDC, it is not a nationwide CDC requirement. The gastrointestinal tract is not a specific common site for HAIs; rather, bacteria are the primary cause. Ensuring restraints are properly secured is important for patient safety but not directly related to reducing HAIs.
Which of these is a correctly stated outcome goal written by the nurse?
- A. The client will walk 2 miles daily by March 19
- B. The client will understand how to give insulin by discharge
- C. The client will regain their former state of health by April 1
- D. The client achieve desired mobility by May 7
Correct Answer: A
Rationale: Outcome goals should be SMART, i.e., Specific, Measurable, Appropriate, Realistic, and Timely. Option A is the only outcome that has a specific behavior (walks daily), with measurable performance criteria (2 miles), and a time estimate for goal attainment (by March 19). Option B lacks specificity in terms of what 'understand how to give insulin' entails, and the timeline is vague ('by discharge'). Option C is not measurable or specific about what 'regain their former state of health' means. Option D does not provide a specific behavior or measurable criteria for 'desired mobility,' and the timeline is the only element that is time-bound.
Which of the following lists the recommended sequence for removing soiled personal protective equipment when preparing to leave a patient's room?
- A. Gown, goggles, mask, gloves, and exit the room.
- B. Gloves, wash hands, remove gown, mask, and goggles.
- C. Gloves, goggles, gown, mask, and wash hands.
- D. Gloves, goggles, gown, mask, and wash hands.
Correct Answer: D
Rationale: The correct sequence for removing soiled personal protective equipment is crucial to prevent contamination. Gloves should always be removed first as they are most likely to be contaminated. Following the removal of gloves, goggles, gown, mask, and finally washing hands is recommended. Choice A is incorrect as gloves should be removed first. Choice B is incorrect as the sequence is not in the recommended order. Choice D is incorrect as gloves should be removed before goggles.
The nurse is planning care for a patient with a wrist restraint. How often should a restraint be removed, the area massaged, and the joints moved through their full range?
- A. Once a shift
- B. Once an hour
- C. Every 2 hours
- D. Every 4 hours
Correct Answer: C
Rationale: Restraints should be removed every 2 hours to prevent complications. Moving the joints through their full range of motion helps prevent muscle shortening and contractures. Massaging the area promotes circulation and reduces the risk of pressure injuries. Removing restraints less frequently could lead to complications like decreased circulation and skin breakdown. Options A, B, and D are incorrect because they do not align with the standard practice of removing restraints every 2 hours to ensure patient safety and well-being.
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.
