1. Which action is appropriate for the nurse to delegate to unlicensed assistive personnel (UAP)?
- A. Listen to a patient's lung sounds for wheezes or rhonchi.
- B. Label specimens obtained during percutaneous lung biopsy.
- C. Instruct a patient about how to use home spirometry testing.
- D. Measure induration at the site of a patient's intradermal skin test.
Correct answer: B
Rationale: Labeling specimens obtained during a percutaneous lung biopsy is a task that can be appropriately delegated to unlicensed assistive personnel (UAP) as it does not require nursing judgment. UAP can perform this task safely under the supervision of a nurse. Listening to a patient's lung sounds for wheezes or rhonchi, instructing a patient about how to use home spirometry testing, and measuring induration at the site of a patient's intradermal skin test all require nursing judgment and interpretation of findings. These tasks should be performed by licensed nursing personnel to ensure accurate assessment and appropriate intervention.
2. When would chest thrusts be performed in an emergency situation?
- A. When performing CPR to initiate cardiovascular circulation.
- B. When assessing responsiveness of an unconscious patient.
- C. When assisting a pregnant woman who is choking.
- D. None of the above examples indicate the need for chest thrusts.
Correct answer: C
Rationale: In the scenario of an emergency where a pregnant woman is choking, chest thrusts are performed to clear the airway obstruction. This technique is used instead of abdominal thrusts to avoid potential harm to the fetus. While chest thrusts are not as effective as abdominal thrusts in clearing obstructions, they are the preferred method in this specific situation. Choices A and B are incorrect as chest thrusts are not typically performed during CPR to initiate cardiovascular circulation or when assessing responsiveness of an unconscious patient. Choice D is incorrect as chest thrusts are indeed warranted when assisting a pregnant woman who is choking.
3. Why should direct care providers avoid glued-on artificial nails?
- A. Interfere with dexterity of the fingers.
- B. Could fall off in a patient's bed.
- C. Harbor microorganisms.
- D. Can scratch a patient.
Correct answer: C
Rationale: Direct care providers, including nurses, should avoid glued-on artificial nails because studies have shown that artificial nails, especially when cracked, broken, or split, create crevices where microorganisms can thrive and multiply. This can lead to an increased risk of transmitting infections to patients. Therefore, the primary reason for avoiding glued-on artificial nails is their potential to harbor harmful microorganisms, making option C the correct choice. Options A, B, and D are incorrect because while they may present some issues, the primary concern is the risk of microbial contamination associated with artificial nails.
4. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?
- A. MAP is the pressure of the arterial pulse.
- B. MAP reflects the stroke volume of the heart.
- C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
- D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.
Correct answer: C
Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.
5. Which contraindication should be assessed for prior to administering an immunization to a child?
- A. Mild cold symptoms
- B. Chronic asthma
- C. Depressed immune system
- D. Allergy to eggs
Correct answer: C
Rationale: Before administering immunizations to children, it is crucial to assess for contraindications. A depressed immune system, such as that seen in conditions like HIV or due to chemotherapy, is a significant contraindication. Immunizations may not be safe or effective in children with compromised immune systems. Mild cold symptoms, although not ideal, are not a contraindication for routine immunizations. Chronic asthma, while a consideration, is not a direct contraindication for routine immunizations. Allergy to eggs is a contraindication for specific vaccines, such as influenza vaccine that is grown in eggs, but it is not a contraindication for all immunizations.
