1. Which of the following organs of the digestive system has a primary function of absorption?

Correct answer: C

Rationale: The small intestine is the correct answer. It is the primary organ responsible for absorption in the digestive system. The stomach's primary function is to break down food through mechanical and chemical digestion. The pancreas produces digestive enzymes to aid in the breakdown of food. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. However, neither the stomach, pancreas, nor gallbladder play the primary role of absorption in the digestive process, making them incorrect choices.

2. Signs of impaired breathing in infants and children include all of the following except:

Correct answer: D

Rationale: Signs of impaired breathing in infants and children can manifest in various ways. Nasal flaring, grunting, and seesaw breathing are all indicative of respiratory distress in pediatric patients. Nasal flaring is the widening of the nostrils with breathing effort, grunting is a sound made during exhalation to try to keep the airways open, and seesaw breathing involves the chest moving in the opposite direction of the abdomen. However, quivering lips are not typically associated with impaired breathing in this context. Lip quivering is a distracter and not a common sign of respiratory distress in infants and children. Therefore, the correct answer is 'quivering lips.'

3. What is an appropriate intervention for the client with suspected genitourinary trauma and visible blood at the urethral meatus?

Correct answer: D

Rationale: When a client presents with suspected genitourinary trauma and visible blood at the urethral meatus, obtaining a voided urine specimen for urinalysis is an appropriate intervention. This helps assess for any urinary tract injuries or abnormalities without further traumatizing the area. Insertion of a Foley catheter (Choice A) should be avoided as it can worsen the existing trauma. Performing an in-and-out catheter specimen (Choice B) involves unnecessary manipulation and can increase the risk of complications. Ordering a urinalysis by the physician (Choice D) may delay the assessment compared to obtaining a direct voided urine specimen.

4. Which of the following is not a primary function of the kidneys?

Correct answer: D

Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.

5. The nurse is caring for a client with decreased cardiac output secondary to heart failure with fluid volume overload. The effects of diminished renal perfusion will have which physiologic response?

Correct answer: B

Rationale: When there is diminished renal perfusion due to decreased cardiac output, the kidneys receive less blood flow. This leads to a decrease in urine output and an increase in fluid retention, as the kidneys are not able to effectively filter and excrete excess fluid. Elevated bicarbonate level and paroxysmal idiopathic narcosis are not typically associated with diminished renal perfusion in heart failure. Therefore, the correct answer is 'Increased fluid retention.'
