Safe and Effective Care Environment NCLEX RN Questions
1. When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?
- A. Five seconds or less
- B. Ten seconds or less
- C. At least 30 seconds
- D. No longer than 60 seconds
Correct answer: B
Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures. Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client. Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.
2. 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.
3. The nurse is teaching a student nurse about the different types of thermometers. When teaching the student about the advantages of the tympanic membrane thermometer (TMT), which statement would the nurse include?
- A. "Measuring temperature using the TMT is cost-effective."?
- B. "The rapid measurement of the TMT is beneficial for uncooperative younger children."?
- C. "TMT is not recommended for measuring core body temperature in newborn infants."?
- D. "TMT is not the preferred method for measuring body temperature in patients with otitis media."?
Correct answer: B
Rationale: The correct answer is "The rapid measurement of the TMT is beneficial for uncooperative younger children." TMT is ideal for young children who may not cooperate for oral temperatures or fear rectal temperatures. However, using TMT for newborn infants is not recommended due to inconsistencies in results. Measuring temperature with TMT is not necessarily cost-effective. The most accurate method for measuring core temperature is through rectal temperatures. TMT may not be the preferred method for patients with otitis media due to potential inaccuracies caused by fluid behind the tympanic membrane.
4. The healthcare provider is preparing to use an otoscope for an examination. Which statement is true regarding the otoscope?
- A. Often used to direct light into the sinuses
- B. Used to examine the structures of the internal ear
- C. Uses a short, broad speculum to help visualize the ear
- D. Directs light into the ear canal and onto the tympanic membrane
Correct answer: D
Rationale: The otoscope is a tool used to examine the ear canal and tympanic membrane, which separates the external and middle ear. It is not intended to direct light into the sinuses or examine the internal structures of the ear. The otoscope typically uses a short, narrow speculum to aid in visualizing the ear canal and tympanic membrane, not a short, broad speculum as mentioned in choice C.
5. What is the anatomic structure located in the middle of the heart that separates the right and left ventricles?
- A. Septum
- B. Sputum
- C. Separator
- D. None of the above
Correct answer: A
Rationale: The correct answer is the septum. The septum is a structure located in the middle of the heart that separates the right and left ventricles. It plays a crucial role in maintaining the separation between the two ventricles to ensure efficient blood flow. The other choices, 'Sputum' and 'Separator,' are incorrect as they do not refer to the anatomic structure in the heart that serves this specific function. 'Sputum' is a term used to describe phlegm or mucus, not an anatomical structure, and 'Separator' is a generic term that does not specifically identify the cardiac structure mentioned in the question.
