1. Based on this strip, what is the interpretation of this rhythm?
- A. Atrial fibrillation.
- B. Ventricular tachycardia.
- C. Normal sinus rhythm.
- D. Second-degree heart block.
Correct answer: C
Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.
2. A nurse in a provider's office is obtaining the health and medication history of a client who has a respiratory infection. The client tells the nurse that she is not aware of any allergies, but that she did develop a rash the last time she was taking an antibiotic. Which of the following information should the nurse give the client?
- A. "Rashes are very common, especially if you have dry skin. Did it go away on its own?"
- B. "Virtually all medications have adverse effects. It sounds like this could have been an adverse effect of the antibiotic."
- C. "It's unlikely that your doctor will prescribe an antibiotic for what seems to be a minor viral infection, so we shouldn't be concerned about that rash."
- D. "We need to document the exact medication you were taking because you might be allergic to it."
Correct answer: D
Rationale: The correct answer is D. If a client reports developing a rash when taking a specific medication, even if they are not aware of any allergies, it is crucial to document this information. This is necessary to prevent future allergic reactions. Identifying the exact medication that caused the rash is essential as the client could have an allergy to it. Providing this information allows healthcare providers to avoid prescribing the same medication again, which could potentially lead to more severe allergic reactions or life-threatening situations. Choices A, B, and C are incorrect because they do not address the importance of documenting the specific medication that caused the adverse reaction or the potential risks of repeating the medication. Simply attributing the rash to common occurrences, adverse effects of medications in general, or assuming the rash is insignificant in the current context can overlook the critical aspect of identifying and avoiding allergens.
3. When caring for a client with diarrhea due to Shigella, which of the following precautions should the nurse take?
- A. Wash hands before and after contact with the client
- B. Wear a surgical mask
- C. Use a face shield
- D. Wear a gown and gloves only
Correct answer: A
Rationale: The correct precaution for Shigella infection is to wash hands thoroughly before and after contact with the client. Shigella is transmitted through the fecal-oral route, so hand hygiene is crucial in preventing its spread. Wearing a surgical mask or face shield is not necessary for Shigella as it is not primarily transmitted through respiratory droplets. While wearing a gown and gloves is important for standard precautions, the key precaution specific to Shigella is proper hand hygiene.
4. A client who is postoperative is verbalizing pain as a 2 on a pain scale of 0-10. Which of the following statements should the nurse identify as an indication that the client understands the preoperative teaching they received about pain management?
- A. "It might help me to listen to music while I'm lying in bed."
- B. "I will use the pain medication as prescribed to manage the pain."
- C. "I will request a different type of pain medication if the pain persists."
- D. "I will ask for a physical therapist to help with the pain."
Correct answer: A
Rationale: The correct answer is A. Listening to music is a non-pharmacological method to help manage mild pain, reflecting an understanding of pain management strategies. It shows the client's grasp of non-pharmacological pain management techniques taught preoperatively. Choice B, while important, only addresses pharmacological pain management, omitting other strategies discussed in preoperative teaching. Choice C jumps to changing medications without considering non-pharmacological methods first, indicating a narrow approach to pain management. Choice D involves a physical therapist, which is not directly related to the pain management strategies typically discussed in preoperative teaching.
5. An adult suffered burns to the face and chest resulting from a grease fire. On admission, the client was intubated, and a 2-liter bolus of normal saline was administered IV. Currently, the normal saline is infusing at 250 ml/hour. The client’s heart rate is 120 beats/minute, blood pressure is 90/50 mmHg, respirations are 12 breaths/minute over the ventilated 12 breaths for a total of 24 breaths/minute, and the central venous pressure (CVP) is 4 mm H2O. Which intervention should the nurse implement?
- A. Increase the rate of normal saline infusion
- B. Infuse an additional bolus of normal saline
- C. Lower the head of the bed to a recumbent position
- D. Bring a tracheostomy tray to the bedside
Correct answer: B
Rationale: The correct intervention is to infuse an additional bolus of normal saline. The client's presentation with a heart rate of 120 beats/minute, hypotensive blood pressure of 90/50 mmHg, and low CVP of 4 mm H2O indicates hypovolemic shock. Administering more normal saline can help in restoring intravascular volume and improving perfusion. Increasing the rate of normal saline infusion (Choice A) is not the best choice as it may lead to fluid overload. Lowering the head of the bed to a recumbent position (Choice C) could worsen hypotension by reducing venous return. Bringing a tracheostomy tray to the bedside (Choice D) is not a priority at this time as the client is already intubated, and the immediate concern is addressing the hypovolemia.
