A client arrives to the emergency department with chest pain after taking sildenafil. Based on the client's history, which medication should the nurse withhold?
Aspirin.
Nitroglycerin.
Morphine.
Heparin.
The Correct Answer is B
Rationale
A. Aspirin is commonly used in the emergency setting for chest pain suspected to be due to acute coronary syndrome (ACS), which includes conditions like myocardial infarction (heart attack). It works by reducing blood clotting and can help alleviate symptoms in some cases. It is typically safe to administer aspirin
B. Sildenafil can interact with nitrates, such as nitroglycerin, and result in a significant drop in blood pressure. Therefore, the nurse should withhold nitroglycerin to prevent potential adverse effects.
C. Morphine is a potent opioid pain medication used in the emergency department for severe pain relief, including chest pain associated with suspected myocardial infarction. It can help reduce pain and anxiety in acute coronary syndromes. It has no significant interaction with sildenafil.
D. Heparin is an anticoagulant medication used to prevent blood clotting. It is often administered in the hospital setting for various indications, such as deep vein thrombosis, pulmonary embolism, or in some cases of acute coronary syndromes.

Correct Answer is D
Explanation
Rationale
A. Using water with 5% dextrose (DW) is appropriate for irrigating certain types of catheters, especially those that require a non-saline solution to maintain patency. However, the choice of irrigation solution should be based on the specific type of catheter and the facility's policies. It does not directly address the immediate issue of the luer-lock syringe.
B. Sending someone else to gather equipment may be necessary in some situations but does not address the current issue of the nurse preparing to irrigate with a luer-lock tipped syringe. This option delays addressing the immediate concern.
C. Applying povidone (such as povidone-iodine solution) to the site is a step in the preparation for aseptic technique but does not address the specific issue of the syringe type or the irrigation process itself.
D. Luer-lock syringes are commonly used for irrigation purposes because they securely attach to irrigation ports, preventing accidental disconnection during the procedure. Directing the nurse to attach the luer-lock syringe ensures that the irrigation can be performed safely and effectively.
Correct Answer is ["12.5"]
Explanation
To calculate the dosage of amoxicillin suspension to be administered every 8 hours, one must first determine the total daily dosage in milligrams. Since 1 gram equals 1000 milligrams, 1.5 grams is equivalent to 1500 milligrams. This total daily dosage needs to be divided into three doses, as it will be administered every 8 hours.
Therefore, each dose will be 1500 mg divided by 3, which equals 500 mg per dose. The medication bottle states that there are 200 mg of amoxicillin in every 5 mL of suspension. To find out how many mL correspond to a 500 mg dose, set up a proportion: 200 mg/5 mL = 500 mg/x mL. Solving for x gives x = (500 mg * 5 mL) / 200 mg, which equals 12.5 mL
Therefore, the nurse should administer 12.5 mL of the amoxicillin suspension every 8 hours.
