A 58-year-old man is diagnosed with cancer of the larynx. Which of the ff. are early symptoms of this cancer?
- A. Anemia and fatigue
- B. A noticeable lump in the neck
- C. Crackles and stridor
- D. Dysphagia or hoarseness
Correct Answer: D
Rationale: Early symptoms of cancer of the larynx typically include persistent hoarseness or a change in the voice quality. This may be due to the tumor affecting the vocal cords. Dysphagia, or difficulty swallowing, can also be an early sign. As the tumor grows, it may cause obstruction or compression in the throat, leading to difficulties in swallowing. These symptoms should prompt further evaluation by a healthcare provider for proper diagnosis and treatment planning. Anemia and fatigue (Choice A) are more general symptoms that can occur in cancer patients but are not typically specific to laryngeal cancer. The presence of a noticeable lump in the neck (Choice B) may indicate swelling of lymph nodes due to cancer spread but is not an early symptom commonly associated with laryngeal cancer. Crackles and stridor (Choice C) are respiratory sounds associated with conditions affecting the airways and are less likely to be early symptoms
Which manifestation is more specific to occur in anaplastic large cell lymphoma (ALCL) than other types of non-Hodgkin lymphoma?

Correct Answer: D
Rationale: Primary mediastinal involvement is a hallmark feature of ALCL.
The mother of a child with a congenital cardiac defect asks the nurse why her child squats after exertion. The nurse should reply that this position:
- A. Reduces muscle aches
- B. Increases cardiac efficiency
- C. Enhances the pull of gravity
- D. Decreases blood volume in the extremities
Correct Answer: B
Rationale: The position of squatting after exertion increases cardiac efficiency in children with congenital cardiac defects, specifically those with Tetralogy of Fallot. By squatting, the child decreases systemic vascular resistance and increases systemic venous return, which helps to enhance cardiac output by improving blood flow to the lungs. This position allows for better oxygenation of the blood and helps alleviate cyanosis in children with Tetralogy of Fallot.
Which of the ff. would the nurse explain to the patient is indicated by a Snellen chart finding 20/80?
- A. The eye can see at 80 feet what the normal eye can see at 20 feet.
- B. The eye can see at 20 feet what the normal eye can see at 80 feet.
- C. The eye can see four times what the normal eye can see.
- D. The eye sees normally.
Correct Answer: A
Rationale: The Snellen chart is a chart used to measure visual acuity. The numbers in a Snellen fraction indicate the distance from which a person with normal eyesight can see the letters on the chart. In the case of 20/80, this means that the person can see at 80 feet what a person with normal eyesight can see at 20 feet. So, option A is correct as it accurately explains what is indicated by a Snellen chart finding of 20/80.
The nurse is aware that a healthy newborn's respirations are:
- A. Regular, abdominal, 40-50 per minute, deep
- B. Irregular, abdominal, 30-60 per minute, shallow
- C. Irregular, initiated by chest wall, 30-60 per minute, deep
- D. Regular, initiated by the chest wall, 40-60 per minute, shallow
Correct Answer: B
Rationale: A healthy newborn's respirations are typically irregular, abdominal, with a rate of 30-60 per minute, and tend to be shallow. Newborns have immature respiratory centers in their brain, leading to irregular breathing patterns compared to adults. Their breathing is usually abdominal due to their diaphragmatic breathing pattern. The normal respiratory rate for a newborn can fluctuate between 30-60 breaths per minute, with shallow breathing being characteristic of their physiology. Regular shallow breathing with occasional periods of apnea is considered normal in newborns and should not be a cause for concern.
