Free PNR 105 Foundations of Nursing Questions

1. A nurse is preparing to administer medications through a nasogastric (NG) tube. What must the nurse do first?
  • A. Crush medications, mix with 5 mL of water, and instill without flushing
  • B. Crush medications as appropriate, flush the tube with 30 mL of water, then give the medications
  • C. Administer medications directly into the tube without dilution
  • D. Give all medications together in one syringe without flushing between them

Explanation

Before administering medications via an NG tube, the nurse must crush medications that can safely be crushed, dilute them with water, and flush the tube with 30 mL of water. This ensures the tube is patent, prevents clogging, and allows proper medication delivery. Each medication should be given separately with additional flushing between drugs to maintain tube patency and accurate dosing.
2. A nurse is teaching a class about end-of-life care. Which of the following are examples of passive euthanasia?
  • A. Assisted suicide
  • B. Withholding artificial feedings or parenteral fluids (IV)
  • C. Not treating pneumonia with antibiotics
  • D. Both B and C

Explanation

Passive euthanasia refers to withholding or withdrawing life-sustaining treatments and allowing a natural death to occur. Examples include withholding artificial feeding or IV fluids and choosing not to treat pneumonia with antibiotics in a terminally ill patient. Assisted suicide is not considered passive euthanasia; it is an active measure where a person intentionally takes action to end life. Passive euthanasia focuses on not starting or discontinuing interventions rather than taking direct action to cause death.
3. If you find your patient on the floor, not breathing, has no pulse, and unconscious, what do you do first?
  • A. Check blood pressure
  • B. Call for help or activate EMS
  • C. Place the patient in recovery position
  • D. Begin CPR

Explanation

The first step when encountering an unresponsive patient with no breathing and no pulse is to call for help or activate emergency medical services (EMS). Early activation ensures that advanced life support and emergency equipment can be mobilized while you begin CPR. This action maximizes the patient’s chance of survival by combining immediate resuscitation with timely advanced interventions.
4. A nurse is preparing to draw a patient’s blood sample. Which patient identifiers should the nurse verify before proceeding?
  • A. Room number and diagnosis
  • B. Patient’s name and date of birth, checked against the wristband
  • C. Patient’s bed number and initials
  • D. Patient’s provider name and procedure type

Explanation

Before drawing blood, at least two patient identifiers must be used to ensure safety and accuracy. The standard practice is to verify the patient’s full name and date of birth, comparing this information to the wristband and the lab requisition form. Room and bed numbers are not reliable identifiers. This process prevents errors such as mislabeling or drawing the wrong patient’s blood.
5. The nurse administering a nasal medication via an atomizer bottle should:
  • A. have the client tilt the head forward.
  • B. have the client sit up straight.
  • C. have the client squeeze the bottle while inhaling.
  • D. leave the other nostril open while giving the medication.

Explanation

For proper administration of nasal medication with an atomizer, the client should gently inhale through the nostril while squeezing the bottle. This coordinated action ensures the medication is carried into the nasal passages and evenly distributed over the mucosa for effective absorption. Failure to inhale while squeezing would cause the spray to remain mostly in the anterior nose, limiting its therapeutic effect.
6. A nurse is assessing a postoperative patient for signs of uncontrolled pain. Which findings would indicate the patient is experiencing poor pain control?
  • A. Smiling, relaxed posture, and normal movement
  • B. Grimacing with movement, holding the body rigid, and guarded behavior
  • C. Steady respiratory rate, normal blood pressure, and calm affect
  • D. Engaging in conversation, walking comfortably, and laughing

Explanation

Signs of uncontrolled pain often include nonverbal cues such as facial grimacing, guarding, or holding the body rigid to avoid movement. Patients may also limit mobility and appear tense or restless. These behaviors signal that pain is not adequately managed and require prompt nursing intervention, even if the patient is not verbally expressing discomfort.
7. A nurse is attending a workshop on providing culturally competent care. How is cultural sensitivity best defined?
  • A. Learning only the language of another culture to improve communication
  • B. Avoiding all discussions about cultural beliefs with patients
  • C. The ability to engage and communicate with an individual from another culture in a manner that demonstrates respect for their cultural norms and beliefs
  • D. Expecting patients to adapt fully to the nurse’s cultural practices

Explanation

Cultural sensitivity means being aware of and respectful toward cultural differences, values, and practices when interacting with others. It requires effective communication that acknowledges and honors cultural norms rather than imposing one’s own. By practicing cultural sensitivity, nurses build trust, reduce misunderstandings, and deliver care that is inclusive and supportive of diverse cultural backgrounds.
8. When you suction your patient through the nasopharyngeal route, what amount of suction do you use?
  • A. 40 to 60 mm Hg
  • B. 80 to 120 mm Hg
  • C. 140 to 160 mm Hg
  • D. 180 to 200 mm Hg

Explanation

The recommended suction pressure for nasopharyngeal suctioning is 80 to 120 mm Hg. This level is strong enough to effectively remove secretions without causing trauma to the delicate mucosal tissues. Using pressures higher than this increases the risk of airway injury, hypoxia, and discomfort, while lower pressures may be ineffective at clearing secretions.
9. A nurse is teaching a patient about different types of surgical procedures. How should the nurse describe exploratory surgery?
  • A. Surgery done to permanently treat a known condition
  • B. Surgery done strictly for cosmetic purposes
  • C. Surgery done to provide further data and determine a diagnosis for a problem
  • D. Surgery done only to relieve symptoms without curing the disease

Explanation

Exploratory surgery is performed when the cause of a patient’s symptoms is unclear and further information is needed for diagnosis. It allows direct visualization and assessment of internal structures, often leading to identification of disease processes such as tumors, infections, or internal bleeding. Unlike curative or palliative surgery, the primary purpose is diagnostic rather than treatment-focused.
10. A nurse begins a shift on a busy medical-surgical unit and will be caring for multiple clients. Which client does the nurse assess first?
  • A. A client who would like some acetaminophen (Tylenol) for a mild headache
  • B. A client who needs discharge teaching about an antibiotic
  • C. A client who just received nitroglycerin for chest pain
  • D. A client who has a question about her daily medications

Explanation

The priority for the nurse is to assess the client who just received nitroglycerin for chest pain. Chest pain may indicate myocardial ischemia or infarction, which is a life-threatening condition. After giving nitroglycerin, it is essential to quickly reassess the client’s pain level, vital signs, and response to the medication. This ensures that the treatment is effective and identifies if additional interventions are needed.
