1. What is a serious adverse reaction to penicillin?

A. Liver Failure
B. Anaphylaxis
C. Respiratory Depression
D. Edema

Correct answer: B

Rationale: The correct answer is B: Anaphylaxis. Anaphylaxis is a severe allergic reaction that can occur as a serious adverse reaction to penicillin. It is a life-threatening condition that requires immediate medical attention. Choices A, C, and D are incorrect. Liver failure is not a typical adverse reaction to penicillin, respiratory depression is more commonly associated with opioid medications, and edema is not a common severe adverse reaction to penicillin.

2. A client has a new prescription for Lisinopril. Which of the following instructions should the nurse include?

A. Avoid salt substitutes.
B. Take this medication at bedtime.
C. Increase your intake of potassium-rich foods.
D. Take this medication with food.

Correct answer: A

Rationale: The correct instruction for a client prescribed Lisinopril is to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, hence the importance of avoiding salt substitutes that may contain potassium. Instructing the client to avoid salt substitutes helps prevent potential adverse effects of increased potassium levels.

3. Which part of the body requires a continuous supply of oxygen and vital nutrients to support life and death?

A. Liver
B. Kidneys
C. Brain
D. Muscles

Correct answer: C

Rationale: The brain requires a continuous supply of oxygen and vital nutrients to support life and prevent death. Oxygen and nutrients are essential for brain function, and any interruption in the supply can lead to serious consequences, including brain damage or death. Therefore, ensuring a constant flow of oxygen and nutrients to the brain is vital for survival and overall health.

4. Which medication is used as a bronchodilator?

A. Warfarin
B. Lovastatin
C. Albuterol
D. Valproate

Correct answer: C

Rationale: Albuterol is the correct answer. It is a medication commonly used as a bronchodilator to treat conditions such as asthma. Albuterol works by relaxing the muscles in the airways, allowing better airflow and making breathing easier for individuals with respiratory conditions. Warfarin (Choice A) is an anticoagulant used to prevent blood clots, Lovastatin (Choice B) is a medication used to lower cholesterol levels, and Valproate (Choice D) is used to treat seizures and bipolar disorder. These medications are not bronchodilators and are used for different medical conditions.

5. A client with heart failure is receiving instructions about laxative use. The client should be advised to avoid which of the following laxatives?

A. Sodium phosphate
B. Psyllium
C. Bisacodyl
D. Polyethylene glycol

Correct answer: A

Rationale: Clients with heart failure often have sodium restrictions. Sodium phosphate can lead to fluid retention due to sodium absorption, which is harmful for individuals with heart failure. Therefore, it should be avoided in this population to prevent exacerbating fluid overload. Psyllium, Bisacodyl, and Polyethylene glycol are safer options for individuals with heart failure as they do not pose the risk of exacerbating fluid overload through sodium retention.
