Nursing Elites

1. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

2. When is sterile technique used?

• A. During strict isolation procedures
• B. After terminal disinfection is performed
• C. For invasive procedures
• D. When protective isolation is necessary

Correct answer: C

Rationale: Sterile technique is utilized during invasive procedures to prevent the introduction of pathogens, minimizing the risk of infections. This strict approach ensures that the procedure is performed in a sterile environment, reducing the chances of contamination and subsequent complications.

3. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

4. A client who is at 38 weeks gestation, is in active labor, and has ruptured membranes is being cared for by a nurse. What action should the nurse take?

• A. Insert an indwelling urinary catheter
• B. Apply fetal heart rate monitor
• C. Initiate fundal massage
• D. Initiate an oxytocin IV infusion

Correct answer: B

Rationale: When caring for a client in active labor with ruptured membranes, the priority action for the nurse is to apply a fetal heart rate monitor. This helps monitor the well-being of the fetus during labor and delivery, enabling timely interventions if any fetal distress is detected. Inserting an indwelling urinary catheter may be required in some cases, but it is not the priority in the given scenario. Fundal massage is typically done after delivery to help the uterus contract and prevent postpartum hemorrhage. Initiating an oxytocin IV infusion may be indicated to augment labor, but it is not the initial action needed in this situation.

5. When caring for a toddler with acute lymphocytic leukemia, in which of the following activities should the toddler participate?

• A. Looking at alphabet flashcards.
• B. Playing with a large plastic truck.
• C. Using scissors to cut out paper shapes.
• D. Watching a cartoon in the dayroom.

Correct answer: B

Rationale: Toddlers with acute lymphocytic leukemia may have compromised immune systems and need to avoid activities that increase infection risk. Playing with a large plastic truck is a safe and engaging activity that does not pose a high risk of infection. This choice also promotes physical activity and creativity, which are beneficial for a toddler's development during illness.
