Which oxygen delivery system would provide the highest concentrations of oxygen to the client?
- A. Venturi mask
- B. Partial rebreather mask
- C. Non-rebreather mask
- D. Simple face mask
Correct Answer: C
Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available.
Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

The nurse is discussing negativism with the parents of a 30-month-old child. How should the nurse advise the parents to best respond to this behavior?
- A. Reprimand the child and give a 15-minute 'time out'
- B. Maintain a permissive attitude for this behavior
- C. Use patience and a sense of humor to deal with this behavior
- D. Assert authority over the child through limit setting
Correct Answer: C
Rationale: Use patience and a sense of humor to deal with this behavior. The nurse should help the parents understand that negativism is a normal part of a toddler's growth towards autonomy. Reacting with patience and humor can help diffuse the situation and maintain a positive relationship with the child. Reprimanding the child and giving a 'time out' (Choice A) may not be effective for addressing negativism and can lead to power struggles. Maintaining a permissive attitude (Choice B) may reinforce negative behavior. Asserting authority through limit setting (Choice D) may be necessary in some situations, but using patience and humor is a more effective initial approach for handling negativism.
A client is scheduled for an Intravenous Pyelogram (IVP). In order to prepare the client for this test, the nurse would:
- A. Instruct the client to maintain a regular diet the day prior to the examination
- B. Restrict the client's fluid intake 4 hours prior to the examination
- C. Administer a laxative to the client the evening before the examination
- D. Inform the client that only 1 x-ray of his abdomen is necessary
Correct Answer: C
Rationale: Administering a laxative to the client the evening before the examination is the correct action. Bowel prep is crucial for an Intravenous Pyelogram (IVP) as it helps in achieving better visualization of the bladder and ureters. Instructing the client to maintain a regular diet the day prior to the examination (Choice A) is not the appropriate preparation for an IVP. Restricting the client's fluid intake 4 hours prior to the examination (Choice B) is not necessary for this test. Informing the client that only 1 x-ray of his abdomen is necessary (Choice D) is not relevant to the preparation process for an IVP.
A woman in her third trimester complains of severe heartburn. What is appropriate teaching by the nurse to help the woman alleviate these symptoms?
- A. Drink small amounts of liquids frequently
- B. Eat the evening meal at least 2-3 hours before bedtime
- C. Take sodium bicarbonate after each meal
- D. Sleep with head propped on several pillows
Correct Answer: D
Rationale: During the third trimester, many women experience heartburn due to the pressure of the growing uterus on the stomach. Elevating the head while sleeping can help prevent gastric contents from refluxing back into the esophagus, thus reducing heartburn symptoms. Drinking small amounts of liquids frequently may exacerbate heartburn by increasing stomach distension. Eating the evening meal just before retiring can also worsen heartburn symptoms as lying down shortly after eating can promote reflux. Taking sodium bicarbonate after each meal is not recommended as it can disrupt the body's natural pH balance and lead to other complications.
The nurse is teaching parents about the treatment plan for a 2-week-old infant with Tetralogy of Fallot. While awaiting future surgery, the nurse instructs the parents to immediately report
- A. Loss of consciousness
- B. Feeding problems
- C. Poor weight gain
- D. Fatigue with crying
Correct Answer: A
Rationale: The correct answer is 'Loss of consciousness.' While parents should report any concerning observations, they need to call the healthcare provider immediately if the infant experiences a loss of consciousness. This change in alertness may indicate anoxia, which can be life-threatening. Tetralogy of Fallot is a congenital heart defect characterized by four main features: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Surgery for Tetralogy of Fallot may be delayed or done in stages. Reporting loss of consciousness is crucial due to the potential seriousness of the condition. Feeding problems, poor weight gain, and fatigue with crying are important issues but do not require immediate reporting like loss of consciousness does.
A nurse is caring for a patient admitted to the emergency room for an ischemic stroke with marked functional deficits. The physician is considering the use of fibrinolytic therapy with TPA (tissue plasminogen activator). Which history-gathering question would not be important for the nurse to ask?
- A. What time did you first notice symptoms consistently appearing?
- B. Have you been taking any blood thinners such as heparin, lovenox, or warfarin?
- C. Have you had another stroke or head trauma in the previous 3 months?
- D. Have you had any blood transfusions within the previous year?
Correct Answer: D
Rationale: The correct answer is 'Have you had any blood transfusions within the previous year?' This question is not relevant in the context of considering fibrinolytic therapy with TPA for an ischemic stroke. Blood transfusions within the previous year do not directly impact the decision to use TPA in the treatment of an acute ischemic stroke. The focus should be on factors such as the time of symptom onset, current medications like blood thinners, and recent history of strokes or head trauma, as these are more directly related to the decision-making process for administering TPA in this emergency situation.
