1. A healthcare professional is preparing to administer an intramuscular injection to a client. Which site is most appropriate for the healthcare professional to use?
- A. Deltoid muscle
- B. Ventrogluteal site
- C. Dorsogluteal site
- D. Rectus femoris site
Correct answer: B
Rationale: The ventrogluteal site is the most appropriate site for administering an intramuscular injection to an adult client. This site is preferred due to its large muscle mass and distance from major nerves and blood vessels, reducing the risk of injury or complications. The deltoid muscle, while commonly used for vaccinations, may not be suitable for certain medications due to its smaller muscle mass. The dorsogluteal site is no longer recommended due to the proximity of the sciatic nerve, which can lead to complications. The rectus femoris site is not commonly used for intramuscular injections in clinical practice.
2. During assessment, what is an indication of thrombophlebitis in a client who has been on bed rest for the past month?
- A. Calf swelling
- B. Elevated blood pressure
- C. Decreased urine output
- D. Generalized rash
Correct answer: A
Rationale: Calf swelling is a common sign of thrombophlebitis, which is inflammation of a vein due to a blood clot. Prolonged immobility can predispose individuals to thrombophlebitis. Calf swelling occurs due to the obstruction of blood flow, causing localized edema. This condition can lead to serious complications like pulmonary embolism if not promptly addressed. Elevated blood pressure, decreased urine output, and a generalized rash are not typically associated with thrombophlebitis. Elevated blood pressure may be linked to other conditions like hypertension, decreased urine output to kidney dysfunction, and a generalized rash to allergic reactions or skin conditions. Therefore, in a client on bed rest, calf swelling should raise suspicion of thrombophlebitis and prompt further evaluation and intervention.
3. What is the structure of deoxyribonucleic acid (DNA)?
- A. single spiral
- B. double helix
- C. sphere
- D. cube
Correct answer: B
Rationale: The correct answer is B: double helix. DNA is structured as a double helix, resembling a twisted ladder made up of two strands of nucleotides. Choice A, single spiral, is incorrect as DNA is not a single spiral structure. Choice C, sphere, is incorrect as DNA does not form a spherical shape. Choice D, cube, is incorrect as DNA does not have a cubic structure. Understanding the double helix structure of DNA is essential as it allows for the storage and transmission of genetic information in living organisms.
4. A client presents to the healthcare provider with fatigue, poor appetite, general malaise, and vague joint pain that improves mid-morning. The client has been using over-the-counter ibuprofen for several months. The healthcare provider makes an initial diagnosis of rheumatoid arthritis (RA). Which laboratory test should the nurse report to the healthcare provider?
- A. Sedimentation rate
- B. White blood cell count
- C. Anti–CCP antibodies
- D. Activated Clotting Time
Correct answer: A
Rationale: The correct answer is A: Sedimentation rate. Sedimentation rate, Anti–CCP antibodies, and C-reactive protein are commonly used laboratory tests to indicate inflammation and help diagnose rheumatoid arthritis. An elevated sedimentation rate is a nonspecific indicator of inflammation in the body, which is often seen in RA. White blood cell count is not specific for RA and is not typically significant in the diagnosis. Anti–CCP antibodies are specific to RA and are useful in confirming the diagnosis. Activated Clotting Time is not relevant to the diagnosis of rheumatoid arthritis as it is not specific to this condition.
5. What is the priority nursing responsibility when a 3-year-old child in a crib is experiencing a tonic-clonic seizure with a clamped jaw?
- A. Apply restraints.
- B. Administer oxygen.
- C. Protect the child from self-injury.
- D. Insert a plastic airway in the child’s mouth.
Correct answer: C
Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints (Choice A) can cause harm by restricting movement during the seizure. While administering oxygen (Choice B) may be necessary, it is not the immediate priority during an active seizure. Inserting a plastic airway (Choice D) is contraindicated as it can lead to injury and is not recommended during a seizure. Protecting the child from self-injury (Choice C) is crucial to prevent harm from uncontrolled movements and potential falls, ensuring the safety of the child.
