A nurse is caring for a client with chest pain. Laboratory Results
1300:
Cardiac troponin T less than 0.5 ng/mL (less than 0.1 ng/mL). LDL 110 mg/dL (less than 130 mg/dL).
Total cholesterol 230 mg/dL (less than 200 mg/dL).
Complete the following sentence by using the list of options: After notifying the provider, the nurse should first:
check a STAT cardiac troponin.
request a prescription for a beta-blocker.
administer sublingual nitroglycerin
Notify the senior
The Correct Answer is C
Administer sublingual nitroglycerin.
Nitroglycerin is a vasodilator that can relieve chest pain caused by myocardial ischemia. The nurse should administer it as soon as possible to improve blood flow to the heart and reduce the risk of myocardial infarction. The nurse should also monitor the client’s blood pressure and heart rate after giving nitroglycerin, as it can cause hypotension and reflex tachycardia.
Choice A is wrong because checking a STAT cardiac troponin is not the first priority.
Cardiac troponin is a biomarker that indicates myocardial injury, but it may not rise until several hours after the onset of chest pain.
Therefore, it is not useful for immediate diagnosis or treatment of acute coronary syndrome. Choice B is wrong because requesting a prescription for a beta-blocker is not the first priority.
Beta-blockers are medications that can lower blood pressure and heart rate, and reduce the oxygen demand of the heart.
They can prevent or reduce the recurrence of chest pain and complications of acute coronary syndrome, but they are not indicated for immediate relief of chest pain.
Choice D is wrong because administering oxygen is not the first priority.
Oxygen therapy can increase the oxygen supply to the heart and reduce ischemia, but it is not necessary for all clients with chest pain.
Oxygen therapy should be based on the client’s oxygen saturation level and clinical condition.
If the client’s oxygen saturation is normal or high, oxygen therapy may not be beneficial and may even be harmful.

Correct Answer is B
Explanation
This is because the retention port is a sterile site that can be accessed by a syringe to aspirate urine without contaminating the specimen or the closed drainage system. The retention port should be cleaned with an alcohol swab before inserting the syringe. The specimen should be transferred to a sterile container and labeled appropriately.
Choice A is wrong because unclamping the collection port below the bag would allow urine to flow out of the bag, which is not sterile and may contain bacteria or sediment.
Choice C is wrong because disconnecting the catheter from the collection tubing would break the closed drainage system and increase the risk of infection.
Choice D is wrong because using the balloon port to obtain the sterile specimen would deflate the balloon that holds the catheter in place and cause trauma to the bladder wall.
Normal ranges for urine characteristics vary depending on the type of analysis, but some general parameters are:
• Color: pale yellow to amber
• Clarity: clear or slightly cloudy
• Odor: faint aromatic
• pH: 4.5 to 8.0
• Specific gravity: 1.005 to 1.030
• Protein: <150 mg/24 hr
• Glucose: negative
• Ketones: negative
• Blood: negative
• Nitrites: negative
• Leukocyte esterase: negative
• Bacteria: <10,000 CFU/mL
Correct Answer is D
Explanation
Herpes zoster is a contraindication for receiving acupuncture treatment because it is an infectious skin disorder that can be transmitted by needles or contact with the affected area. Acupuncture should not be performed on areas of skin that are inflamed, ulcerated, or have sensory deficits.
Choice A is wrong because hypertension is not a contraindication for acupuncture. However, some caution is advised when needling points that may lower blood pressure, such as LI 4, LI 11, ST 36, and SP 6.
Choice B is wrong because hypothyroidism is not a contraindication for acupuncture. In fact, some studies suggest that acupuncture may have beneficial effects on thyroid function and symptoms of hypothyroidism.
Choice C is wrong because obesity is not a contraindication for acupuncture.
Acupuncture may help with weight loss by regulating appetite, metabolism, and hormones.
Some of the absolute contraindications for acupuncture include pregnancy (especially certain points that may induce labor or abortion), medical and surgical emergencies, malignant tumors, bleeding disorders, and the use of a demand pacemaker. Some of the relative contraindications include drug or alcohol intoxication, lack of consent, immune deficiency, abnormal heart valves, and fear of needles.
Normal ranges for blood pressure are 120/80 mmHg or lower for systolic and diastolic pressure respectively.
Normal ranges for thyroid-stimulating hormone (TSH) are 0.4 to 4.0 mIU/L. Normal ranges for body mass index (BMI) are 18.5 to 24.9 kg/m2.
