1. Which of the following is classified as a prerenal condition that affects urinary elimination?

• A. Nephrotoxic medications
• B. Pericardial tamponade
• C. Neurogenic bladder
• D. Polycystic kidney disease

Correct answer: B

Rationale: A prerenal condition is one that causes reduced urinary elimination by affecting the blood flow to the kidneys. Pericardial tamponade is a condition that impacts the heart's ability to pump sufficient blood, leading to decreased blood flow to vital organs such as the kidneys. This reduction in blood flow to the kidneys can result in decreased urine production. The other choices, such as nephrotoxic medications, neurogenic bladder, and polycystic kidney disease, do not primarily affect the blood flow to the kidneys and are not classified as prerenal conditions that impact urinary elimination.

2. Digestion, elimination, and ___________ are the three functions of the digestive system.

• A. constriction
• B. relaxation
• C. absorption
• D. peristalsis

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.

3. When counting an infant's respirations, which technique is correct?

• A. Watching the chest rise and fall
• B. Observing the movement of the abdomen
• C. Placing a hand across the infant's chest
• D. Using a stethoscope to listen to the breath sounds

Correct answer: B

Rationale: The correct technique for counting an infant's respirations is to observe the movement of the abdomen. Infants typically have more diaphragmatic breathing than thoracic, so watching the abdomen provides a more accurate count. Placing a hand on the chest or listening with a stethoscope can alter the infant's breathing pattern and provide inaccurate results. Therefore, options A, C, and D are incorrect methods for counting an infant's respirations. By observing the movement of the abdomen, healthcare providers can accurately assess an infant's respiratory rate without influencing their breathing pattern.

4. A healthcare professional is preparing to administer an enteral feeding through a gastrostomy tube. Before administering the feeding, the healthcare professional aspirates some stomach contents and checks the pH. The result is 3.9. What is the next action of the healthcare professional?

• A. Administer the feeding as ordered
• B. Pull the feeding tube out approximately 3 cm
• C. Flush the feeding tube with 60 cc of water
• D. Contact the physician

Correct answer: A

Rationale: When the pH of the aspirated stomach contents is 4 or less, it indicates that the gastrostomy tube is in the stomach, confirming correct placement. A pH of 3.9 falls within this range, so the healthcare professional can proceed with administering the enteral feeding. There is no need to adjust the tube placement, flush with water, or contact the physician in this situation as the tube is appropriately positioned for feeding.

5. A 60-year-old patient has been treated for pneumonia for the past 6 weeks. The patient is seen today in the clinic for an unexplained weight loss of 10 pounds over the last 6 weeks. Which is an appropriate rationale for this patient's weight loss?

• A. Chronic diseases such as hypertension do not usually cause weight loss.
• B. Weight loss is more likely due to underlying medical conditions than unhealthy eating habits.
• C. Unexplained weight loss often accompanies short-term illnesses.
• D. Weight loss is not typically caused by mental health dysfunctions.

Correct answer: C

Rationale: Unexplained weight loss in a patient with pneumonia could indicate an underlying short-term illness or a chronic condition like endocrine disease, malignancy, depression, anorexia nervosa, or bulimia. Hypertension is not commonly associated with weight loss; it usually leads to weight gain due to fluid retention. Unhealthy eating habits are less likely to explain significant unexplained weight loss over a short period. Mental health dysfunctions can affect appetite but are not typically primary causes of significant unexplained weight loss.
