1. Which of the following signs or symptoms indicates a possible nutritional deficiency?
- A. Subcutaneous fat at the waist and abdomen
- B. Presence of papillae on the surface of the tongue
- C. Straight arms and legs
- D. Pale conjunctiva
Correct answer: D
Rationale: A client with poor nutritional intake may have pale mucous membranes surrounding the eye, or the conjunctiva. This area should normally be pink, indicating good circulation and a lack of irritation or dryness. Improper nutrition can manifest as numerous signs in the body, including bowed legs, pale mucous membranes, a smooth or beefy tongue, and poor muscle tone. Subcutaneous fat at the waist and abdomen is not a sign of nutritional deficiency but rather of excess fat deposition. The presence of papillae on the surface of the tongue is normal and not indicative of a nutritional deficiency. Straight arms and legs are also typical anatomical features and not specifically related to nutritional deficiencies.
2. In which of the following ways can a nurse promote sleep for a client experiencing insomnia?
- A. Assist the client in using the bathroom one hour after going to bed
- B. Give the client a massage before bedtime
- C. Tuck bed sheets and blankets tightly around the client once settled in bed
- D. Give the client a pair of socks to wear if their feet become cold
Correct answer: D
Rationale: A nurse can promote sleep for a client experiencing insomnia by addressing factors that may hinder sleep. Cold feet can disrupt sleep, so providing the client with socks to keep their feet warm can enhance comfort and aid in promoting sleep. The correct answer focuses on a direct intervention to address a specific issue that can impact sleep quality. Choices A, B, and C do not directly address the issue of cold feet, which is a common problem that can interfere with sleep in individuals with insomnia. Assisting the client to use the bathroom, giving a massage in the morning, or tucking in bed sheets tightly do not target the discomfort caused by cold feet, making them less effective interventions for promoting sleep in this scenario.
3. What procedure examines a portion of the large intestine with an endoscope?
- A. Colposcopy
- B. Sigmoidoscopy
- C. Upper GI
- D. Cardiac catheterization
Correct answer: B
Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.
4. To which of the following do the CDC Standard precautions recommendations apply?
- A. Patients with diagnosed infections only
- B. Blood or body fluids with visible blood only
- C. All body fluids including sweat
- D. All patients receiving care in hospitals
Correct answer: D
Rationale: The correct answer is 'All patients receiving care in hospitals.' Standard precautions apply to all patients in healthcare settings, regardless of their infection status. These recommendations include all body fluids except sweat, non-intact skin, and mucous membranes. Choice A is incorrect as standard precautions are not limited to patients with diagnosed infections. Choice B is incorrect as standard precautions extend beyond blood or body fluids with visible blood. Choice C is incorrect as sweat is an exception to the body fluids covered under standard precautions.
5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?
- A. Yield a falsely low blood pressure
- B. Yield a falsely high blood pressure
- C. Be the same, regardless of cuff size
- D. Vary as a result of the technique of the person performing the assessment
Correct answer: B
Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
