Nursing Elites

1. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

2. A nurse manager is developing a protocol for an urgent care clinic that often cares for clients who do not speak the same language as clinical staff. Which of the following instructions should the nurse include?

• A. Use a professional interpreter service
• B. Nurse to interpret
• C. Provide translation services for a nominal fee to clients
• D. Evaluate the clients' understanding at regular intervals

Correct answer: B

Rationale: In situations where there is a language barrier between healthcare providers and patients, it is essential to ensure accurate communication. Using professional interpreter services is the most appropriate choice to ensure clear and precise communication. Relying on the client's children for interpretation may not guarantee accurate or confidential communication. Asking the nurse to interpret can lead to miscommunication or misunderstanding of important medical information. Providing translation services for a nominal fee to clients may not always be feasible or culturally appropriate. Regularly evaluating the client's understanding helps ensure that information is effectively communicated and comprehended.

3. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.

4. 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.

5. A patient is admitted to the hospital with complaints of nausea, vomiting, diarrhea, and severe abdominal pain. Which of the following would immediately alert the healthcare provider that the patient has bleeding from the GI tract?

• A. Complete blood count
• B. Guaiac test
• C. Vital signs
• D. Abdominal girth

Correct answer: B

Rationale: A positive guaiac test is used to detect the presence of occult (hidden) blood in the stool, suggesting bleeding from the gastrointestinal tract. It is a rapid screening test that can provide immediate information to the healthcare provider about possible gastrointestinal bleeding in patients presenting with symptoms such as nausea, vomiting, diarrhea, and severe abdominal pain.
