Nursing Elites

1. A newborn baby exhibits a reflex that includes hand opening, abducted, and extended extremities following a jarring motion. Which of the following correctly identifies the reflex?

• A. ATNR reflex
• B. Startle reflex
• C. Grasping reflex
• D. Moro reflex

Correct answer: D

Rationale: The Moro reflex, also known as the startle reflex, is the correct answer. This reflex is characterized by the baby's response to a sudden head movement or loud noise, causing them to open their hands, extend their arms, and then bring them back towards their body. The characteristics mentioned in the question - hand opening, abducted, and extended extremities following a jarring motion - align with the Moro reflex. The asymmetrical tonic neck reflex (ATNR) involves the head turning to one side with extension of the same side's arm and leg, not the described characteristics. The grasping reflex involves the baby's response to touch on the palm, causing them to grasp an object. While the Moro reflex is often referred to as the startle reflex due to its response to sudden stimuli, the specific characteristics described in the question match the Moro reflex.

2. A nurse suspects a patient is developing Bell's Palsy. The nurse wants to test the function of cranial nerve VII. Which of the following would be the most appropriate testing procedures?

• A. Test the taste sensation over the back of the tongue and activation of the facial muscles.
• B. Test the taste sensation over the front of the tongue and activation of the facial muscles.
• C. Test the sensation of the facial muscles and sensation of the back of the tongue.
• D. Test the sensation of the facial muscles and sensation of the front of the tongue.

Correct answer: B

Rationale: The facial nerve (VII) is responsible for motor function to the face and sensory function to the anterior two-thirds of the tongue. Therefore, to appropriately test the function of cranial nerve VII, the most appropriate testing procedures involve assessing the taste sensation over the front of the tongue (sensory) and activation of the facial muscles (motor). Option B, 'Test the taste sensation over the front of the tongue and activation of the facial muscles,' is the correct answer. Choices A, C, and D are incorrect because they do not involve the correct combination of sensory testing over the front of the tongue and motor activation of the facial muscles, which are key functions associated with cranial nerve VII.

3. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.

4. A nurse is working in a pediatric clinic, and a 25-year-old mother comes in with a 4-week-old baby. The mother is stressed out about the loss of sleep, and the baby exhibits signs of colic. Which of the following techniques should the nurse teach the mother?

• A. Distraction of the infant with a red object
• B. Prone positioning techniques
• C. Tapping reflex techniques
• D. Neural warmth techniques

Correct answer: D

Rationale: Neural warmth techniques involve the caregiver providing a warm, soothing touch to the baby, which can help to lower the baby's agitation level and promote relaxation. This technique is beneficial for calming colicky babies. Choices A, B, and C are incorrect because distraction with a red object, prone positioning, and tapping reflex techniques are not effective methods for managing colic in infants. Red object distraction is not a proven technique for soothing colicky babies. Prone positioning is not recommended for infants due to the risk of sudden infant death syndrome (SIDS). Tapping reflex techniques are not recognized as effective interventions for colic.

5. A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?

• A. hyperkalemia
• B. hypernatremia
• C. hypokalemia
• D. hypomagnesemia

Correct answer: C

Rationale: When a client is receiving drug therapy with furosemide and digitalis, the nurse should anticipate the development of hypokalemia due to the potassium-wasting effects of furosemide. Hypokalemia can potentiate digitalis toxicity. While hyperkalemia is a concern with some medications, it is not typically associated with furosemide and digitalis. Furosemide can lead to hyponatremia, not hypernatremia, due to its diuretic effect. Hypomagnesemia, though a possible imbalance, is not the most likely to occur in this scenario as furosemide and digitalis are more commonly associated with hypokalemia.
