Clients with myastherda gravis, Guillain - Barre Syndrome or amyothrophic sclerosis experience:
- A. Progressive deterioration until death
- B. Deficiencies of essential neurotransmitter
- C. Increased risk of respiratory complications
- D. Involuntary twitching of small muscle group
Correct Answer: C
Rationale: The correct answer is C: Increased risk of respiratory complications. Clients with myasthenia gravis, Guillain-Barre Syndrome, or amyotrophic lateral sclerosis may experience respiratory muscle weakness, leading to difficulty breathing and an increased risk of respiratory complications such as pneumonia or respiratory failure. This is due to the involvement of the muscles responsible for breathing in these conditions. Progressive deterioration until death (A) is not always the case and varies depending on the condition and individual. Deficiencies of essential neurotransmitters (B) is not a common symptom in these conditions. Involuntary twitching of small muscle groups (D) is not a characteristic symptom of these neurological disorders.

Which of the following client outcomes best describes the parameters for achieving the outcome?
- A. The client will eat a well-balanced diet.
- B. The client will consume a 2,400-calorie diet, with three meals and two snacks, starting tomorrow.
- C. The client will cleanse his wound with soap and water and apply a dry sterile dressing.
- D. The client will be without pain in 24 hours.
Correct Answer: B
Rationale: The correct answer is B because it provides specific, measurable, achievable, relevant, and time-bound (SMART) parameters for achieving the outcome. It outlines the calorie intake, meal frequency, and start date, which allows for clear monitoring and evaluation of progress. Choice A is too vague and lacks specificity. Choice C focuses on wound care, not dietary goals. Choice D lacks specificity and a timeframe, making it difficult to measure success. In conclusion, choice B is the best option as it aligns with effective goal-setting principles.
As part of primary cancer prevention program, an oncology nurse answers questions from the public at health fair. When someone asks about the laryngeal cancer, the nurse should explain that:
- A. Laryngeal cancer is one of the most preventable types of cancer
- B. Inhaling polluted air isn’t a risk factor for laryngeal cancer
- C. Laryngeal cancer occurs primarily in women
- D. Adenocarcinoma accounts for most cases of laryngeal cancer
Correct Answer: A
Rationale: The correct answer is A: Laryngeal cancer is one of the most preventable types of cancer. This is because the primary risk factors for laryngeal cancer are largely related to lifestyle choices such as smoking, excessive alcohol consumption, and exposure to certain occupational hazards. By avoiding these risk factors, individuals can significantly reduce their chances of developing laryngeal cancer.
Choices B, C, and D are incorrect:
B: Inhaling polluted air isn’t a risk factor for laryngeal cancer - This is incorrect as exposure to polluted air can contribute to the development of laryngeal cancer.
C: Laryngeal cancer occurs primarily in women - This is incorrect as laryngeal cancer occurs more frequently in men than in women.
D: Adenocarcinoma accounts for most cases of laryngeal cancer - This is incorrect as squamous cell carcinoma is the most common type of laryngeal cancer, not adenocarcin
A client is undergoing a diagnostic workup for suspected thyroid cancer. What is the most common form of thyroid cancer in adults?
- A. Follicular carcinoma
- B. Anaplastic carcinoma
- C. Medullary carcinoma
- D. Papillary carcinoma
Correct Answer: D
Rationale: The correct answer is D: Papillary carcinoma. This is the most common form of thyroid cancer in adults, accounting for about 80% of cases. It is typically slow-growing and has a good prognosis. Papillary carcinoma arises from the follicular cells of the thyroid gland. Follicular carcinoma (choice A) is less common than papillary carcinoma and arises from the follicular cells as well. Anaplastic carcinoma (choice B) is a highly aggressive and rare form of thyroid cancer. Medullary carcinoma (choice C) originates from the parafollicular C cells of the thyroid gland and is not as common as papillary carcinoma. Therefore, the most appropriate choice is D, papillary carcinoma, due to its high prevalence and relatively favorable prognosis.
Wilma, His sister and a nurse is suctioning the tracheostomy tube of James. Which of the following, if made by Wilma indicates that she is committing an error?
- A. Hyperventilating James with 100% oxygen before and after suctioning
- B. Instilling 3 to 5 ml normal saline to loosen up secretion
- C. Applying suction during catheter withdrawal
- D. Suction the client every hour
Correct Answer: A
Rationale: The correct answer is A because hyperventilating James with 100% oxygen before and after suctioning can lead to oxygen toxicity. The rationale is as follows:
1. Hyperventilation with 100% oxygen can lead to increased oxygen levels in the blood, potentially causing oxygen toxicity.
2. Oxygen toxicity can result in lung damage and other complications.
3. It is not recommended to administer 100% oxygen continuously, especially in high concentrations.
Therefore, Wilma committing an error by hyperventilating James with 100% oxygen. Other choices are incorrect because B is a common practice to help loosen secretions, C is correct suctioning technique, and D is a reasonable frequency for suctioning depending on the client's condition.
Which part of the brain controls breathing?
- A. Medulla
- B. Cerebrum
- C. Cerebellum
- D. Thalamus
Correct Answer: A
Rationale: The correct answer is A: Medulla. The medulla is located in the brainstem and plays a crucial role in controlling involuntary functions like breathing. It contains the respiratory center, which regulates the rate and depth of breathing. The medulla sends signals to the diaphragm and intercostal muscles to control breathing. The cerebrum (B) is responsible for higher brain functions, not breathing control. The cerebellum (C) coordinates movement and balance, not breathing. The thalamus (D) relays sensory information to the cerebral cortex, not involved in breathing regulation.
