Nokea
The nurse understands that which of the ff. best describes the action of propanolol (Inderal)?
- A. It increases heart rate
- B. It decreases fluid volume
- C. It decreases cardiac output
- D. It increases cardiac contractility
Correct Answer: C
Rationale: Propranolol (Inderal) is a non-selective beta-blocker that works by blocking beta receptors in the heart and blood vessels. By blocking these receptors, propranolol decreases the effects of adrenaline, leading to a decrease in heart rate, blood pressure, and cardiac output. This results in a reduction in the workload of the heart, making it an effective medication for conditions such as hypertension, angina, and certain types of arrhythmias. Overall, the action of propranolol leads to a decrease in cardiac output, contrary to the options that suggest an increase in heart rate, fluid volume, or cardiac contractility.

Which intervention should the nurse implement to maintain the skin integrity of the preterm newborn?
- A. Cleanse skin with a gentle alkaline-based soap and water.
- B. Cleanse skin with a neutral pH solution only when necessary.
- C. Thoroughly rinse skin with plain water after bathing in a mild hexachlorophene solution.
- D. Avoid cleaning skin.
Correct Answer: B
Rationale: Preterm newborns have delicate skin that is more susceptible to damage and irritation. Using a neutral pH solution for cleansing helps to maintain the skin's natural acidity and prevent disruption of the skin barrier. It is important to avoid over-bathing or using harsh alkaline-based soaps that can strip the skin of its natural oils and cause dryness or irritation. Cleansing the skin only when necessary helps to protect the fragile skin of preterm newborns and reduce the risk of skin breakdown or injury.
A patient has cloudy penile discharge. For which additional symptoms of urethritis should the nurse assess?
- A. Throat or rectal infection
- B. Chancres or vesicles on the genitals
- C. Painful and frequent urination
- D. Oliguria and flank pain
Correct Answer: C
Rationale: Cloudy penile discharge is a common symptom of urethritis, which is inflammation of the urethra usually caused by an infection, such as a sexually transmitted infection (STI) like gonorrhea or chlamydia. Painful and frequent urination are also classic symptoms of urethritis. Painful urination, or dysuria, may occur due to the irritation and inflammation of the urethra. Frequency of urination can be a result of the body's response to the infection or inflammation. Therefore, assessing for these additional symptoms helps in confirming the diagnosis of urethritis and determining the appropriate treatment for the patient.
A patient has allergic rhinitis. In planning care for the patient, the nurse understands that if the patient does not remain compliant with the treatment regimen, the patient is at risk for developing which of the following?
- A. Sinusitis
- B. Lymphadenopathy
- C. Anaphylaxis
- D. Angioedema
Correct Answer: A
Rationale: Allergic rhinitis is characterized by inflammation of the nasal passages due to exposure to allergens. If a patient with allergic rhinitis does not remain compliant with the treatment regimen, such as taking antihistamines or using nasal corticosteroids, it can lead to chronic inflammation and congestion of the nasal passages. Over time, this chronic inflammation can predispose the patient to developing complications such as sinusitis, which is the inflammation of the sinuses. Sinusitis can result in symptoms such as facial pain, pressure, nasal congestion, and fever. Therefore, non-compliance with treatment in allergic rhinitis can increase the risk of developing sinusitis as a complication.
A client with a nagging cough makes an appointment to see the physician after reading that this symptom is one of the seven warning signs of cancer. What is another warning sign of cancer?
- A. Persistent nausea
- B. Indigestion
- C. Rash
- D. Chronic ache or pain
Correct Answer: D
Rationale: Chronic ache or pain is another warning sign of cancer. Persistent pain that does not go away and continues for weeks or months could be a symptom of cancer. It is important not to ignore persistent pain and to consult a healthcare provider if such pain exists, as it could be a sign of an underlying issue like cancer. Early detection and treatment are key in managing cancer and improving outcomes for patients.
