Which of the following procedures does the nurse understand is used to correct otosclerosis?
- A. Myringotomy
- B. Mastoidectomy
- C. Myringoplasty
- D. Stapedectomy
Correct Answer: D
Rationale: The correct answer is D: Stapedectomy. This procedure is used to correct otosclerosis by removing the stapes bone and replacing it with a prosthetic device. This restores normal hearing by allowing sound waves to travel through the ear properly. Myringotomy (A) is a procedure to drain fluid from the middle ear, not to correct otosclerosis. Mastoidectomy (B) is the removal of infected mastoid air cells, not related to otosclerosis. Myringoplasty (C) is a surgical procedure to repair a perforated eardrum, not used for otosclerosis. Stapedectomy is the most appropriate choice for correcting otosclerosis as it directly addresses the abnormal bone growth in the middle ear.

During outcome identification and planning, from what part of the nursing diagnoses are outcomes derived?
- A. The defining characteristics
- B. The related factors
- C. The problem statement
- D. The database
Correct Answer: C
Rationale: During outcome identification and planning, outcomes are derived from the problem statement of the nursing diagnoses. This is because the problem statement clearly defines the patient's health issue or condition that needs to be addressed, thus guiding the development of specific, measurable, and achievable outcomes. The defining characteristics (choice A) describe the signs and symptoms of the health problem but do not directly lead to outcome identification. The related factors (choice B) represent the potential causes or contributing factors to the health problem and are not used to derive outcomes. The database (choice D) consists of the patient's health history, assessment data, and laboratory findings, which are essential for diagnosing but do not directly determine outcomes. Therefore, the correct answer is C as it directly informs the outcomes to be achieved.
Maintaining the infusion rate of hyperalimentation solutions is a nursing responsibility. What side effects would you anticipate from too rapid infusion rate?
- A. Cellular dehydration and potassium
- B. Hypoglycemia and hypovolemia
- C. Potassium excess and CHF
- D. Circulatory overload and hypoglycemia SITUATION: In the recall of the fluids and electrolytes, the nurse should be able to understand the calculations and other conditions related to loss or retention.
Correct Answer: D
Rationale: Rationale:
1. Rapid infusion of hyperalimentation solutions can lead to circulatory overload due to increased fluid volume in the circulatory system.
2. Circulatory overload can result in symptoms such as hypertension, tachycardia, and edema.
3. Hypoglycemia can occur as a result of excess insulin release due to the sudden increase in glucose from the hyperalimentation solution.
Summary:
A. Cellular dehydration and potassium: Incorrect. Rapid infusion would lead to fluid overload, not dehydration.
B. Hypoglycemia and hypovolemia: Incorrect. Hypovolemia is unlikely with rapid infusion, and hypoglycemia is a possible side effect.
C. Potassium excess and CHF: Incorrect. Rapid infusion may cause circulatory overload, not CHF, and potassium excess is not a common side effect.
D. Circulatory overload and hypoglycemia: Correct. These are the most likely side effects of rapid
What is a critical component of the evaluation phase in the nursing process?
- A. Determine if client outcomes have been achieved
- B. Revise the client’s health history
- C. Establish priorities for care
- D. Formulate new nursing diagnoses
Correct Answer: A
Rationale: Step 1: Evaluation phase assesses if client outcomes have been achieved.
Step 2: Determines effectiveness of nursing interventions.
Step 3: Validates if goals are met or adjustments are needed.
Step 4: Reflects on the success of the care plan.
Step 5: Choice A is correct as it directly relates to evaluating the effectiveness of nursing care.
Summary:
- Choice B is incorrect as revising health history is part of assessment.
- Choice C is incorrect as establishing priorities is part of the planning phase.
- Choice D is incorrect as formulating new nursing diagnoses is part of the diagnosis phase.
A newly admitted patient who is morbidly obese asks the nurse for assistance to the bathroom for the first time. Which action should the nurse take initially?
- A. Ask for at least two other assistive personnel to come to the room.
- B. Medicate the patient to alleviate discomfort while ambulating.
- C. Review the patient’s activity orders.
- D. Offer the patient a walker.
Correct Answer: A
Rationale: Step-by-step rationale for why answer A is correct:
1. Safety: Morbidly obese patients are at higher risk of falls during transfers.
2. Assistance: Having two other personnel ensures safe transfer.
3. Weight distribution: Distributing the patient's weight among multiple helpers reduces strain.
4. Proper body mechanics: Allows for proper positioning and technique while assisting.
Summary of why other choices are incorrect:
B. Medication doesn't address the safety concern of transferring a morbidly obese patient.
C. Reviewing activity orders is not the immediate action needed for the patient's first bathroom transfer.
D. Offering a walker may not provide sufficient support for a morbidly obese patient during the transfer.
What deficits would the nurse expect in a right-handed person experiencing a stroke affecting the left side of the cortex?
- A. Expressive aphasia and paralysis on the right side of the body.
- B. Expressive aphasia and paralysis on the left side of the body. .
- C. Dysarthria and paralysis on the right side of the body.
- D. Mixed aphasia and paralysis on the right side of the body.
Correct Answer: B
Rationale: The correct answer is B: Expressive aphasia and paralysis on the left side of the body. In a right-handed person, the left side of the brain controls language (Broca's area) and motor function for the right side of the body. A stroke affecting the left side of the cortex would lead to expressive aphasia (difficulty speaking) due to damage to Broca's area and paralysis on the right side of the body due to motor function impairment. Choices A, C, and D are incorrect because they do not align with the known neurological functions of the brain regions affected by the stroke.
