Nokea
A hospital has been the site of an increased incidence of hospital-acquired pneumonia (HAP). What is an important measure for the prevention of HAP?
- A. Administration of prophylactic antibiotics
- B. Administration of pneumococcal vaccine to vulnerable individuals
- C. Obtaining culture and sensitivity swabs from all newly admitted patients
- D. Administration of antiretroviral medications to patients over age 65
Correct Answer: B
Rationale: Pneumococcal vaccination reduces the incidence of pneumonia, hospitalizations for cardiac conditions, and deaths in the general older adult population. A one-time vaccination of pneumococcal polysaccharide vaccine (PPSV) is recommended for all patients 65 years of age or older and those with chronic diseases. Antibiotics are not given on a preventative basis and antiretroviral medications do not affect the most common causative microorganisms. Culture and sensitivity testing by swabbing is not performed for pneumonia since the microorganisms are found in sputum.

The nurse is caring for a patient who has been in a motor vehicle accident and the care team suspects that the patient has developed pleurisy. Which of the nurses assessment findings would best corroborate this diagnosis?
- A. The patient is experiencing painless hemoptysis
- B. The patients arterial blood gases (ABGs) are normal, but he demonstrates increased work of breathing
- C. The patients oxygen saturation level is below 88%, but he denies shortness of breath
- D. The patients pain intensifies when he coughs or takes a deep breath
Correct Answer: D
Rationale: The key characteristic of pleuritic pain is its relationship to respiratory movement. Taking a deep breath, coughing, or sneezing worsens the pain. The patients ABGs would most likely be abnormal and shortness of breath would be expected.
The public health nurse is administering Mantoux tests to children who are being registered for kindergarten in the community. How should the nurse administer this test?
- A. Administer intradermal injections into the childrens inner forearms
- B. Administer intramuscular injections into each childs vastus lateralis
- C. Administer a subcutaneous injection into each childs umbilical area
- D. Administer a subcutaneous injection at a 45-degree angle into each childs deltoid
Correct Answer: A
Rationale: The purified protein derivative (PPD) is always injected into the intradermal layer of the inner aspect of the forearm. The subcutaneous and intramuscular routes are not utilized.
The nurse is assessing a patient who has a 35 pack-year history of cigarette smoking. In light of this known risk factor for lung cancer, what statement should prompt the nurse to refer the patient for further assessment?
- A. Lately, I have this cough that just never seems to go away
- B. I find that I dont have nearly the stamina that I used to
- C. I seem to get nearly every cold and flu that goes around my workplace
- D. I never used to have any allergies, but now I think Im developing allergies to dust and pet hair
Correct Answer: A
Rationale: The most frequent symptom of lung cancer is cough or change in a chronic cough. People frequently ignore this symptom and attribute it to smoking or a respiratory infection. A new onset of allergies, frequent respiratory infections, and fatigue are not characteristic early signs of lung cancer.
The nurse caring for a patient recently diagnosed with lung disease encourages the patient not to smoke. What is the primary rationale behind this nursing action?
- A. Smoking decreases the amount of mucus production
- B. Smoke particles compete for binding sites on hemoglobin
- C. Smoking causes atrophy of the alveoli
- D. Smoking damages the ciliary cleansing mechanism
Correct Answer: D
Rationale: In addition to irritating the mucous cells of the bronchi and inhibiting the function of alveolar macrophage (scavenger) cells, smoking damages the ciliary cleansing mechanism of the respiratory tract. Smoking also increases the amount of mucus production and distends the alveoli in the lungs. It reduces the oxygen-carrying capacity of hemoglobin, but not by directly competing for binding sites.
A new employee asks the occupational health nurse about measures to prevent inhalation exposure of the substances. Which statement by the nurse will decrease the patients exposure risk to toxic substances?
- A. Position a fan blowing on the toxic substances to prevent the substance from becoming stagnant in the air
- B. Wear protective attire and devices when working with a toxic substance
- C. Make sure that you keep your immunizations up to date to prevent respiratory diseases resulting from toxins
- D. Always wear a disposable paper face mask when you are working with inhalable toxins
Correct Answer: B
Rationale: When working with toxic substances, the employee must wear or use protective devices such as face masks, hoods, or industrial respirators. Immunizations do not confer protection from toxins and a paper mask is normally insufficient protection. Never position a fan directly blowing on the toxic substance as it will disperse the fumes throughout the area.
