An adolescent has been diagnosed with Chlamydia infection. Which medication should the nurse expect to be prescribed for this condition?

Correct Answer: B

Rationale: Chlamydia infection is commonly treated with antibiotics, such as azithromycin or doxycycline. Azithromycin is often preferred due to its convenience of a single oral dose. It is effective in treating Chlamydia infections in both adolescents and adults. Ceftriaxone, penicillin G benzathine, and acyclovir are used to treat different types of infections and are not appropriate choices for Chlamydia infection.

Correct Answer: B

Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia, which can be dangerous for a child with chronic renal failure. Sodium polystyrene sulfonate (Kayexalate) is a medication commonly used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestine, promoting the elimination of excess potassium through the gastrointestinal tract. This helps lower the serum potassium levels and prevent complications associated with hyperkalemia. Spironolactone (Aldactone) is a potassium-sparing diuretic and should be avoided in a child with hyperkalemia. Lactulose (Cephulac) is a laxative and does not directly address high potassium levels. Calcium carbonate (Calcitab) is a calcium supplement and is not indicated for managing hyperkalemia.

Correct Answer: A

Rationale: Digoxin is a medication commonly used to treat infants with heart conditions. One of the primary concerns with digoxin therapy is the risk of toxicity, which can lead to serious cardiac arrhythmias. Bradycardia, or a heart rate less than 60 beats per minute, is a common sign of digoxin toxicity. Therefore, if a 6-month-old infant receiving digoxin has an apical pulse rate of less than 60 beats/min, the nurse should notify the practitioner and withhold the medication to prevent further complications.

Correct Answer: D

Rationale: High-density lipoproteins (HDLs) are often referred to as "good" cholesterol because they help remove other forms of cholesterol from your bloodstream, including low-density lipoproteins (LDLs) which are considered "bad" cholesterol. HDLs play a protective role in preventing cardiovascular disease as they transport cholesterol from the arteries to the liver for excretion. Therefore, having higher levels of HDL cholesterol is associated with a lower risk of heart disease, making it an important focus when discussing hyperlipidemia prevention strategies.

Correct Answer: C

Rationale: In the case of a female client age 66 admitted for a nephrolithotomy with a urinary tract infection, the best nursing action is to encourage fluid intake of 3000ml/day. Adequate hydration helps in flushing out the bacteria causing the urinary tract infection and can prevent further complications. Increasing fluid intake also helps in preventing the formation of new kidney stones. Administering IV fluids and blood transfusions may be necessary based on the patient's overall condition, but the priority action in this case is to promote increased oral fluid intake. Administering narcotic analgesics as prescribed can help manage pain related to the nephrolithotomy procedure, but it does not directly address the urinary tract infection. Suggesting taking herbs or spices to increase food palatability is not the priority in this situation and may not contribute significantly to the management of the urinary tract infection.
