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.

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.
In assisting a physician to perform a thoracentesis to Mr. Sy, how should the nurse postion a patient with pleural effusion of the left lung?
- A. supine with the left arm extended over the head
- B. sitting at the side of the bed with both arms resting on alocked overbed table
- C. high fowler's with both arms resting on pillows
- D. semi-fowlers with both arms resting on pillows
Correct Answer: B
Rationale: In performing a thoracentesis for a patient with pleural effusion of the left lung, the patient should be positioned sitting at the side of the bed with both arms resting on an overbed table. This position allows for better access to the left lung area and helps the patient maintain a comfortable and stable position during the procedure. Sitting position also helps to expand the intercostal spaces, making it easier for the physician to access the pleural fluid. Additionally, having both arms resting on an overbed table helps the patient remain still and reduce the risk of injury during the procedure. Therefore, this position is the most suitable for performing a thoracentesis for a patient with pleural effusion of the left lung.
is softening of the bones as result of nutritional deficiencies or limited exposure to sunlight :
- A. COXA
- B. scoliosis
- C. Rickets
- D. Talipes
Correct Answer: C
Rationale: Rickets is a condition that involves softening and weakening of the bones in children, usually due to a vitamin D deficiency, inadequate calcium intake, or lack of exposure to sunlight. Vitamin D is essential for the absorption of calcium and phosphorus in the body, which are important for bone health. Without sufficient vitamin D, the body is unable to properly mineralize the bones, leading to softening and deformities. Common symptoms of rickets include bowed legs, delayed growth, and muscle weakness. Treatment typically involves vitamin D supplementation, dietary changes, and adequate exposure to sunlight.
When teaching a preoperative older patient, which of the following is a technique to improve learning?
- A. Sit in front of window in bright sunlight.
- B. Speak in high tone.
- C. Use small, white-on-black printed
- D. Eliminate background noise. materials.
Correct Answer: D
Rationale: Eliminating background noise is a beneficial technique when teaching an older patient preoperatively. Older individuals may have age-related hearing impairments, making it difficult for them to focus and understand information in the presence of background noise. By minimizing distractions and background noise, the older patient can better concentrate on the information being taught and improve their learning experience.
The nurse should expect a client with hypothyroidism to report which health concerns?
- A. Increased appetite and weight loss
- B. Nervousness and tremors
- C. Puffiness of the face and hands
- D. Thyroid gland swelling
Correct Answer: C
Rationale: Hypothyroidism is characterized by an underactive thyroid gland that does not produce enough thyroid hormone. This hormonal imbalance can lead to symptoms such as slow metabolism, weight gain, fatigue, cold intolerance, constipation, and puffiness of the face and hands. The slowed metabolic rate can also cause fluid retention, resulting in the characteristic puffiness associated with hypothyroidism. Increased appetite and weight loss are not typical symptoms of hypothyroidism, as the condition is more commonly associated with weight gain. Nervousness and tremors are more indicative of hyperthyroidism, where the thyroid gland is overactive. Thyroid gland swelling, known as goiter, can occur in various thyroid disorders but is not specific to hypothyroidism.
