Fundamentals of Nursing Nursing Process Questions

Correct Answer: C

Rationale: The correct answer is C because decreased pulse rate and widened pulse pressure are not signs of hypovolemia. In hypovolemia, the body tries to compensate by increasing the heart rate and narrowing the pulse pressure to maintain adequate blood flow. A is incorrect as dry mucous membranes and soft eyeballs are signs of dehydration. B is incorrect as increased hematocrit and hemoglobin are indicators of hemoconcentration in hypovolemia. D is incorrect as increased lethargy and confusion can be seen in severe hypovolemia due to poor perfusion of vital organs.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to directly gather patient data through observation, palpation, percussion, and auscultation. It helps in assessing the patient's overall health status, identifying any abnormalities, and establishing a baseline for further care. Reviewing literature (A) helps in evidence-based practice but does not directly collect patient data. Checking orders for tests (B) and ordering medications (D) involve actions based on data collected rather than collecting the data itself.

Correct Answer: B

Rationale: The correct answer is B: Potato. Potatoes are high in potassium, which is essential for various bodily functions. Potatoes can help increase potassium intake in patients who require it. Bread, eggs, and cereal are not as rich in potassium as potatoes. Increasing intake of these foods won't provide the necessary boost in potassium levels needed for the patient.

Correct Answer: A

Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action. Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.

Correct Answer: B

Rationale: The correct answer is B: To prevent cerebrospinal fluid (CSF) leakage. 1. Positioning is crucial to prevent CSF leakage as the spinal block is administered into the sub-arachnoid space where CSF is present. 2. Incorrect Answers: A: Positioning is not related to preventing confusion in this context. C: Seizures are not typically associated with spinal block anesthesia. D: Cardiac arrhythmias are not directly impacted by the client's positioning for a spinal block.
