Why must clients who will undergo diagnostic skin test avoid taking antihistamine or cold preparations for at least 48-72 hrs before testing?
- A. Antihistamines may increase the potential for excessive bleeding
- B. Antihistamines may aggravate the allergic reaction
- C. Antihistamines may increase the potential for false negative results
- D. Antihistamines may cause wheezing
Correct Answer: C
Rationale: The correct answer is C because antihistamines can suppress the immune response that the skin test is designed to detect, leading to false negative results. By inhibiting the body's allergic response, antihistamines can mask the presence of an allergy, giving the false impression that the individual is not allergic to a particular substance. This can lead to misdiagnosis and improper treatment. Choices A, B, and D are incorrect because antihistamines do not affect bleeding, aggravate allergic reactions, or cause wheezing in the context of a skin test.

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.

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.

Step 3: Repeat thrusts until the object is dislodged. Other choices are incorrect as they do not address airway obstruction. A: Increasing medication absorption is not a purpose of the Heimlich maneuver. C: Preventing falls and D: Maintaining extremities in proper position are not related to choking emergencies.
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: Step-by-step rationale for why choice A is correct:
1. Laryngeal cancer is strongly linked to smoking and alcohol consumption.
2. Both smoking and alcohol use are modifiable risk factors, meaning they can be prevented.
3. By avoiding smoking and excessive alcohol intake, individuals can significantly reduce their risk of developing laryngeal cancer.
4. Therefore, laryngeal cancer is considered one of the most preventable types of cancer.
Summary of why the other choices are incorrect:
B. Inhaling polluted air can be a risk factor for laryngeal cancer, so this statement is inaccurate.
C. Laryngeal cancer occurs more frequently in men than women, so this statement is incorrect.
D. Squamous cell carcinoma, not adenocarcinoma, is the most common type of laryngeal cancer, making this statement incorrect.

- A. Risk for infection
- B. Urinary retention
- C. Excessive fluid volume
- D. Hypothermia

This imbalance can result in excessive fluid volume. A) Risk for infection is not directly related to Addison's disease. B) Urinary retention is not a common symptom of Addison's disease. D) Hypothermia is not a typical manifestation of Addison's disease.
Which of the ff. does the nurse understand are the reasons a patient with pulmonary edema is given morphine sulphate? i.To reduce anxiety iv.To increase BP ii.To relieve chest pain v.To reduce preload and afterload iii.To strengthen heart contractions
- A. 2 and 4
- B. 3 and 5
- C. 1 and 5
- D. 2 and 3
Correct Answer: C
Rationale: The correct answer is C because morphine sulfate is given to a patient with pulmonary edema to reduce anxiety (i) and to reduce preload and afterload (v). Morphine sulfate does not increase blood pressure (ii), relieve chest pain (iii), or strengthen heart contractions (iv) in the context of pulmonary edema. Choice A is incorrect because it includes increasing BP, which is not a reason for giving morphine sulfate in this case. Choice B is incorrect because it includes strengthening heart contractions, which is not a reason for administering morphine sulfate. Choice D is incorrect because it includes relieving chest pain, which is not a primary purpose of giving morphine sulfate to a patient with pulmonary edema.
