D) "If my breathing gets worse, I should keep taking extra puffs of the inhaler until I can breathe more easily." Rationale: ipratropium is medication prescribed to prevent wheezing and shortness of breath associated with COPD, it is not a fast-acting medication which means it would not help for immediate relief of shortness of breath
The patient's wife is taking rifampin to prevent her from developing a tuberculosis infection. Which statement by the wife indicates that further teaching is needed? A. "Because my oral contraceptives will not work while I am taking rifampin, I will use another form of birth control." B. "I will take the medication for one week and then stop." C. "I will avoid prolonged exposure to the sun." D. "My urine may turn a reddish color when taking rifampin."
Correct answer: B Rationale: Antitubercular therapy is taken for long periods of time, often 24 months. Although this patient does not have an active infection at this time and is taking the rifampin to prevent an infection, the nurse should further investigate the length of time the medication is ordered. All other statements are true.

The patient will receive the drug and supportive care to help him tolerate the anti tubercular therapy. C. The patient will remain on isolation precautions until his cough clears. D. There is nothing that can be done with this patient.
Correct answer: B Rationale: It must be recognized that the urgency of treating a potentially fatal infection may have to be balanced against any prevailing contraindications. In extreme cases, patients are sometimes given a drug to which they have some degree of allergy with supportive care that enables them at least to tolerate the medication. Examples of such supportive care are treatment with antipyretics (e.g., acetaminophen), antihistamines (e.g., diphenhydramine), or even corticosteroids (e.g., prednisone, methylprednisolone).

A hospitalized patient has an order for ketorolac (Toradol). The nurse notes that the order is only for 5 days. What is the reason for this? A) The medication can cause severe kidney and GI effects B) There are concerns about addiction to the drug C) The patient's pain should subside by that time D) the medication loses its effectiveness over time
A) the medication can cause severe kidney and GI effects Rationale: Toradol is an NSAID that inhibits prostaglandins which are responsible for dilating blood vessels leading to the kidneys. Absence of the prostaglandins can therefore lead to kidney ischemia and cause acute kidney injury. Toradol also has anticoagulant properties which can cause GI bleeding if there is any pre-existing ulcer or nick in the GI tract.
Which assessment information obtained by the nurse for a patient with aortic stenosis would be the most important to report to the heart care provider? A) The patient complains of chest pain associated with ambulation B) A thrill is palpable at the 2nd intercostal space, right sternal border C) a loud systolic murmur is audible along the right sternal border D) the point of maximum impulse (PMI) is at the left midclavicular line
A) the patient complains of chest pain associated with ambulation Rationale: the other answers would be expected findings associated with aortic stenosis while chest pain during ambulation may indicate worsening of the condition

A) weak, nonproductive cough
The nurse is teaching a patient about the inhaler Advair (salmeterol and fluticasone). Which statements by the patient indicates a correct understanding of this medication? Select all that apply A) "I will rinse my mouth with water after each does" B) "This medication is taken twice a day, every 12 hours" C) "I need to use this inhaler whenever I feel short of breath, but make sure it's not less than 4 hours between doses." D) "I will call my doctor if I notice white patches inside my mouth." E) "I can take this inhaler if I get short of breath while exercising."
A, B, D Rationale: Advair is a long-lasting medication used to prevent bronchospasms that is to be taken on a daily basis. It is not intended for quick relief of shortness of breath. Also, fluticasone is a corticosteroid which increases the chances of having thrush grow on the tongue which can be prevented by rinsing the mouth after administration

What is an aortic dissection?
The inner wall of the aorta breaks open but the outer wall does not. Bleeding occurs between this space.
Answer: A. Following defibrillation, CPR is immediately initiated if a perfusable rhythm is not initiated. The client may need to be shocked again, but chest compressions must begin first.
The patient who has recently been experiencing runs of ventricular tachycardia suddenly loses consciousness. The patient is defibrillated, and the rate returns as the following. What should the nurse do first? A) Begin compressions B) Shock the client again immediately C) Prepare for intubation D) Administer adenosine
Answer: B. Atrial flutter places the client at high risk for development of clot formation in the atria. Because the client is stable at this time, cardioversion or adenosine would not be performed at this time. Before cardioversion can occur in a patient, anticoagulant therapy should be begun at least 48 hours beforehand if possible.
The patient with a history of hypertension and diabetes has the following rhythm strip. The patient's vitals are as follows: BP 145/89, HR 90, SpO2 95%, RR 19.
