Choice A Rationale:
Hemorrhage is not a direct risk associated with antibiotic use and diarrhea. While severe diarrhea can lead to fluid  loss and potentially hypovolemia, it's not the most significant risk in this context. 
Antibiotics themselves don't typically cause bleeding issues unless they specifically interfere with clotting factors,  which isn't common. 
The nurse should monitor for signs of bleeding, but it's not the primary concern based on the patient's history of  antibiotic use and diarrhea. 

Choice B Rationale: 
Cardiovascular collapse is a serious complication, but it's not directly linked to antibiotic use and diarrhea. It can occur due to various factors like severe dehydration, electrolyte imbalances, or underlying heart conditions. The nurse should be vigilant for signs of cardiovascular instability, but it's not the most likely risk in this scenario. 
Choice C Rationale: 
Electrolyte imbalances are a significant concern for patients with diarrhea, especially those on antibiotics. Antibiotics can disrupt the balance of gut bacteria, which play a crucial role in electrolyte absorption. Diarrhea further exacerbates electrolyte loss through fluid loss. 
Key electrolytes to monitor include: 
Potassium: Essential for nerve and muscle function, including the heart. Low potassium (hypokalemia) can lead to  muscle weakness, fatigue, cramps, and potentially heart arrhythmias. 
Sodium: Vital for fluid balance and nerve signaling. Low sodium (hyponatremia) can cause confusion, seizures, and  coma. 
Chloride: Also important for fluid balance and acid-base balance. 
Magnesium: Crucial for muscle function, nerve transmission, and energy production. Low magnesium  (hypomagnesemia) can cause muscle cramps, tremors, and heart arrhythmias. 
The nurse should closely monitor the patient's electrolyte levels and watch for signs of imbalance, such as muscle  weakness, fatigue, cramps, confusion, or heart rhythm abnormalities. 

Choice D Rationale: 
Respiratory paralysis is not a typical risk associated with antibiotic use or diarrhea.
It's more commonly linked to neuromuscular disorders, certain medications, or severe electrolyte imbalances  (especially low potassium or calcium). 
While the nurse should be aware of potential respiratory complications, it's not the most likely concern in this case. 
 

Choice A rationale: 
Tertiary health promotion and illness prevention focus on managing existing health conditions and preventing complications.  Administering a nebulized bronchodilator to a client who is short of breath directly addresses an existing respiratory problem,  aiming to relieve symptoms and prevent further respiratory distress. This intervention falls under tertiary prevention because  it targets a client already experiencing respiratory symptoms. 
Key points: 
Bronchodilators open constricted airways, easing airflow and breathing. 
Nebulizers deliver medication directly to the lungs, providing rapid relief. 
Shortness of breath is a common symptom of respiratory conditions like asthma and COPD. 
Prompt treatment of respiratory symptoms can prevent worsening of the condition and potential complications. 
Choice B rationale: 
Teaching a client about the risks of light cigarettes is an example of primary prevention. It aims to prevent lung disease before  it develops by educating individuals about the harms of smoking.
Choice C rationale: 
Advocating for more explicit warning labels on cigarette packages is a form of secondary prevention. It targets at-risk  populations (smokers) to encourage behavior change and reduce smoking rates, ultimately lowering the incidence of lung  disease. 
Choice D rationale: 
Assisting with lung function testing is a diagnostic procedure, not a tertiary prevention intervention. It helps to identify  respiratory problems but doesn't directly manage or prevent them.
 

Choice A rationale: 
Straight catheters are single-use catheters that are inserted into the bladder to drain urine and then immediately removed.  They are not suitable for long-term use in clients with obstructed urethras because they would need to be inserted repeatedly,  causing discomfort and potential trauma to the urethral tissues. Additionally, the obstruction itself would make it difficult or  impossible to insert a straight catheter. 
Choice B rationale: 
Indwelling urethral catheters, also known as Foley catheters, are inserted into the bladder and remain in place for a period of  time. They are typically used for clients who cannot void on their own or who require continuous bladder drainage. However,  they are not the best option for clients with obstructed urethras for the following reasons:
The presence of the catheter within the urethra can further irritate or damage the already obstructed tissues. The balloon that holds the catheter in place could potentially worsen the obstruction. 
The risk of urinary tract infections (UTIs) is increased with indwelling catheters. 
Choice C rationale: 
Intermittent urethral catheters are inserted into the bladder to drain urine and then removed. They are typically used by  clients who can self-catheterize several times a day. However, they are not suitable for clients with complete prostatic  obstruction, as the obstruction would make it difficult or impossible to insert the catheter. 
Choice D rationale: 
Suprapubic catheters are inserted directly into the bladder through a small incision in the abdomen, bypassing the urethra  entirely. This makes them the most suitable option for clients with obstructed urethras, as it eliminates the need to pass a  catheter through the obstructed area. Suprapubic catheters offer several advantages in this situation: 
They avoid further irritation or damage to the urethral tissues. 
They provide a more comfortable and convenient option for long-term bladder drainage. 
They may reduce the risk of UTIs compared to indwelling urethral catheters.
