A novice nurse collects data on a newly admitted client. Upon evaluation of this data, the nurse provides an erroneous interpretation. What is a corrective action for this interpretation?
- A. Encourage the novice nurse to independently observe the same situation with a peer, validate the data, and discuss the situation afterward.
- B. Encourage the novice nurse to develop his or her own tool for data collection.
- C. Encourage the novice nurse to collect and interpret the data for the client repeatedly, until the novice nurse arrives at the correct interpretation.
- D. Encourage the novice nurse to meet with the nurse manager to discuss the situation and seek mentoring for communication skills.
Correct Answer: A
Rationale: The correct answer is A because it encourages the novice nurse to independently observe the situation with a peer, validate the data, and discuss afterward. This approach promotes reflection, peer learning, and validation of collected data, which are essential for learning and growth. It allows the nurse to self-assess and correct errors through discussion and feedback.
Choice B is incorrect as it does not address the need for validation and peer feedback. Choice C is incorrect as repeating the same mistake without guidance does not promote learning. Choice D is incorrect as meeting with the nurse manager may not provide the same level of peer learning and validation as observing with a peer.
A nurse is gathering information about a patients habits and lifestyle patterns. Which method of data collection will the nurse use that will best obtain this information?
- A. Carefully review lab results.
- B. Conduct the physical assessment.
- C. Perform a thorough nursing health history.
- D. Prolong the termination phase of the interview.
Correct Answer: C
Rationale: The correct answer is C: Perform a thorough nursing health history. This method is the best for gathering information about a patient's habits and lifestyle patterns because it involves asking specific questions related to the patient's daily routines, habits, and lifestyle choices. By obtaining a comprehensive health history, the nurse can gather valuable information about the patient's diet, exercise habits, sleep patterns, stress levels, substance use, and other lifestyle factors that may impact their health. Reviewing lab results (A) may provide some information but not specifically about habits and lifestyle. Conducting a physical assessment (B) focuses more on the patient's physical condition rather than lifestyle. Prolonging the termination phase of the interview (D) is not a method of data collection and does not focus on gathering information about habits and lifestyle patterns.
Why should clients who take warfarin (Coumadin) refrain from food items such as green leafy vegetables and soybeans?
- A. Because the foods contain Vitamin K, which reduces the anti coagulant effect of the medication
- B. Because the foods contain Vitamin K, which increases the anti coagulant effect of the medication
- C. Because the foods help stimulate salivation
- D. Because the foods minimize the volume of food consumption
Correct Answer: A
Rationale: The correct answer is A because green leafy vegetables and soybeans are high in Vitamin K, which counteracts the anticoagulant effect of warfarin. Warfarin works by inhibiting Vitamin K-dependent clotting factors in the liver. By consuming Vitamin K-rich foods, the medication's effectiveness is reduced, leading to an increased risk of blood clot formation. Choices B, C, and D are incorrect because they do not address the specific interaction between Vitamin K and warfarin in affecting coagulation. Choice B suggests the opposite effect of what actually occurs. Choices C and D are irrelevant to the pharmacological mechanism of warfarin.
What is the last step when inserting an IV cannula?
- A. Secure the cannula with tape.
- B. Document the insertion site, date, and type of cannula used.
- C. Assess the site
- D. Place a sterile dressing over the insertion site. INFLAMMATORY AND INFECTIOUS DISTURBANCES Caring for clients with upper respiratory infections
Correct Answer: A
Rationale: The correct answer is A: Secure the cannula with tape. This is the last step in inserting an IV cannula to ensure it stays in place and prevents dislodgement or movement. Securing the cannula with tape helps maintain proper positioning and prevents accidental removal. Documenting the insertion site, date, and type of cannula used (B) is important but typically done earlier in the process. Assessing the site (C) should be done before securing the cannula to ensure proper placement. Placing a sterile dressing over the insertion site (D) is also important, but it usually comes before securing the cannula with tape to maintain a clean and sterile environment.
