The nurse evaluates a patient with a newly implanted pacemaker. Based upon the EKG strip which area of the heart is being paced? See attachment.
- A Ventricle
- B Atrium
- C Atrioventricular node
- D Sinoatrial node
Explanation
Explanation
The presence of a paced spike followed by a wide QRS complex suggests that the pacemaker is pacing the ventricle. In ventricular pacing, the pacemaker stimulates the ventricle to contract, which is shown by the wide QRS complex that follows the pacing spike, as the electrical impulse travels through the ventricles instead of the normal conduction system。Correct Answer Is:
A. VentricleA 22-year-old female patient arrives at the ED accompanied by an older male who states he is her "friend." The patient avoids eye contact, appears anxious, and allows the male to answer all questions. When the nurse asks the patient about her symptoms, the male interrupts repeatedly and insists on staying in the room. The patient has bruising in various stages of healing and no identification or insurance information. Which action should the nurse take first?
- Notify hospital security to detain the companion.
- Ask the patient direct questions about her trafficking situation in front of the companion.
- Seek an opportunity to separate the patient from the companion for a private conversation.
- Call local law enforcement immediately.
Explanation
Explanation
The situation described is concerning, as it suggests the patient may be a victim of abuse or human trafficking. The patient’s avoidance of eye contact, anxiety, and the companion’s controlling behavior (interrupting and insisting on staying in the room) are red flags for potential coercion or manipulation. The nurse should first separate the patient from the companion to provide an opportunity for the patient to speak freely in a private, safe environment. This allows the nurse to assess the situation more thoroughly and obtain accurate information about the patient’s condition, without the risk of the companion influencing the conversation。Correct Answer Is:
C. Seek an opportunity to separate the patient from the companion for a private conversation.A patient with carcinoma of the lung develops syndrome of inappropriate antidiuretic hormone (SIADH) as a complication of cancer. The nurse anticipates which intervention will be indicated?
- Decreased oral sodium intake
- Monitor serum sodium blood levels
- Increased fluid intake
- IV administration of 5% Dextrose in water
Explanation
Explanation
In SIADH, the body retains too much water due to the excessive release of antidiuretic hormone (ADH), which leads to dilutional hyponatremia (low sodium levels in the blood). The nurse should closely monitor serum sodium levels to assess the severity of hyponatremia and to guide treatment. The goal is to correct sodium imbalances and prevent complications like seizures or neurological damage。Correct Answer Is:
B. Monitor serum sodium blood levelsA nurse is caring for a patient with metastatic breast cancer. The nurse finds that the patient has developed facial and periorbital edema, and has distention of veins of the face, neck, and chest. Based on these findings, the nurse should suspect which oncologic emergency?
- Third space syndrome
- Spinal cord compression
- Tumor lysis syndrome
- Superior vena cava syndrome
Explanation
Explanation
The symptoms described—facial and periorbital edema, as well as distention of veins in the face, neck, and chest—are classic signs of superior vena cava syndrome (SVCS). SVCS occurs when the superior vena cava is compressed or obstructed, often by a tumor (in this case, metastatic breast cancer). This compression impairs the return of blood from the head, neck, and upper extremities, leading to venous congestion, swelling, and distention of veins. SVCS is an oncologic emergency that requires prompt diagnosis and treatment, such as stenting or radiation therapy to relieve the obstruction。Correct Answer Is:
D. Superior vena cava syndromeA nurse is assessing a patient for a suspected anaphylactic reaction following administration of contrast media. Which finding requires an immediate nursing intervention?
- Urticaria
- Stridor
- Vomiting
- Hypotension
Explanation
Explanation
Stridor is a high-pitched, wheezing sound typically caused by upper airway obstruction, and it is a severe and life-threatening sign of anaphylaxis. This indicates respiratory distress and suggests that the airway is compromised. Stridor should be treated as an emergency in a patient with suspected anaphylaxis, as the airway can become completely obstructed, leading to respiratory failure. Immediate action, including administration of epinephrine, oxygenation, and possible airway management (e.g., intubation), is required。Correct Answer Is:
B. StridorThe family member of a patient asks the nurse the purpose of charcoal administration for their family member who ingested poison. What is the nurse's best response?
- Absorbs toxins from the gastrointestinal tract.
- Induces vomiting and removes all the remaining toxins.
- Decreases the possibility of bleeding from absorbed toxins.
- Prevents cardiac dysrhythmias that may result from absorbed toxins.
Explanation
Explanation
Activated charcoal is used to treat certain types of poisoning or drug overdoses by absorbing toxins in the gastrointestinal (GI) tract. The charcoal binds to the ingested toxin, preventing its absorption into the bloodstream, and allows it to be excreted from the body through the stool. This helps to limit the effects of the poison or drug before it can be absorbed into the body. Activated charcoal is not absorbed into the body and works primarily in the GI tract to trap the toxins。Correct Answer Is:
A. Absorbs toxins from the gastrointestinal tract.A patient in shock develops anasarca and signs of liver failure. Which stage of shock does the nurse recognize?
- Initial
- Compensatory
- Progressive
- Refractory
Explanation
Explanation
The progressive stage of shock is characterized by worsening tissue perfusion and the onset of organ dysfunction due to severe hypoperfusion. In this stage, patients may develop fluid retention leading to anasarca (severe generalized edema) as a result of increased capillary permeability and the body’s attempt to compensate for inadequate blood flow. Liver failure is also a sign of progressive shock, as the liver is highly sensitive to changes in perfusion and oxygenation. The kidneys, liver, and heart begin to fail due to prolonged hypoperfusion。Correct Answer Is:
C. ProgressivePrescribed: Begin Nitroglycerine infusion at 20 mL/hr x 12 hours
Available: Nitroglycerine 100mg/250mL D5W
How many mcg/min the patient is receiving?
- 132 mcg/min
- 100 mcg/min
- 160 mcg/min
- 150 mcg/min
Explanation
Explanation
- First, determine the concentration of nitroglycerine:
- Available concentration: 100 mg in 250 mL。
- Therefore, concentration is:
100 mg ÷ 250 mL=0.4 mg/mL
- Available concentration: 100 mg in 250 mL。
- Convert the prescribed infusion rate from mL/hr to mL/min:
- The prescribed infusion rate is 20 mL/hr。
- Convert to mL/min:
20 mL/hr ÷ 60 min/hr=0.33 mL/min
- The prescribed infusion rate is 20 mL/hr。
- Calculate the amount of nitroglycerine delivered per minute in mg:
- Infusion rate: 0.33 mL/min
- Concentration: 0.4 mg/mL
- Therefore, the amount of nitroglycerine delivered per minute is:
0.33 mL/min×0.4 mg/mL=0.132 mg/min - Convert mg/min to mcg/min:
- Since 1 mg = 1000 mcg:
0.132 mg/min×1000=132 mcg/min - Final Answer: A. 132 mcg/min
The patient is receiving 132 mcg/min of nitroglycerine。
- Infusion rate: 0.33 mL/min
Correct Answer Is:
A. 132 mcg/minA patient diagnosed with pericarditis complains of level 6 (0 to 10 scale) chest pain with deep breathing. Which of these ordered PRN medications would be most appropriate for the nurse to administer?
- Fentanyl 2 mg IV
- Morphine sulfate 6 mg IV
- Acetaminophen 650 mg PO
- Ibuprofen 800 mg PO
Explanation
Explanation
Pericarditis is an inflammation of the pericardium, often resulting in sharp, pleuritic chest pain, especially with deep breathing. The most appropriate treatment for pain relief in pericarditis is nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Ibuprofen helps reduce the inflammation and provides analgesia, which is key in treating pericarditis-related pain. It is effective for treating the underlying inflammatory process, rather than simply masking the pain。Correct Answer Is:
D. Ibuprofen 800 mg POThe nurse is caring for a patient who needs a valve replacement with a mechanical valve. Which information does the nurse need to include in patient teaching prior to surgery?
- Information regarding lifelong anticoagulation therapy.
- Antibiotic therapy for 6-8 weeks post-operative.
- Avoiding rigorous activity three years post-operative.
- Yearly EKG readings after valve replacement.
Explanation
Explanation
Patients who receive a mechanical heart valve are required to undergo lifelong anticoagulation therapy because mechanical valves carry a higher risk of forming blood clots. Anticoagulants like warfarin are commonly prescribed to reduce the risk of clot formation, and it is essential for the patient to be educated on the importance of regular monitoring (such as INR levels), adjusting medication dosages, and the long-term management of anticoagulation therapy. Proper education will help prevent complications such as stroke or embolism。Correct Answer Is:
A. Information regarding lifelong anticoagulation therapy.How to Order
