Adult Health 2 Exam 1
1. The nurse is teaching a client about the administration of a subcutaneous injection. Which site is most appropriate for this type of injection?
- A. Deltoid muscle
- B. Dorsogluteal muscle
- C. Ventrogluteal muscle
- D. Abdomen
Correct answer: D
Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.
2. Which nursing activity is within the scope of practice for the practical nurse?
- A. Complete an admission assessment in the normal newborn nursery
- B. Discontinue a central venous catheter that has become dislodged
- C. Observe a client rotate the subcutaneous site for an insulin pump
- D. Monitor a continuous narcotic epidural for a postoperative client
Correct answer: C
Rationale: The correct answer is C: 'Observe a client rotate the subcutaneous site for an insulin pump.' This activity is within the scope of practice for a practical nurse as it involves observing and ensuring proper technique for using an insulin pump, which aligns with their training and responsibilities. Choices A, B, and D are beyond the typical scope of practice for a practical nurse. Completing an admission assessment for a newborn nursery is usually performed by a registered nurse. Discontinuing a dislodged central venous catheter and monitoring a narcotic epidural require advanced skills and knowledge, usually carried out by registered nurses or advanced practice nurses.
3. The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?
- A. Bilateral leg swelling.
- B. Sudden onset of chest pain.
- C. Gradual onset of dyspnea.
- D. Decreased breath sounds on auscultation.
Correct answer: C
Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.
4. Which structures are located in the subcutaneous layer of the skin?
- A. Sebaceous and sweat glands
- B. Melanin and keratin
- C. Sensory receptors and hair follicles
- D. Adipose cells and blood vessels
Correct answer: D
Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.
5. The nurse is preparing to administer an intramuscular injection to a 6-month-old infant. Which site is most appropriate for this injection?
- A. Deltoid muscle
- B. Ventrogluteal muscle
- C. Dorsogluteal muscle
- D. Vastus lateralis muscle
Correct answer: D
Rationale: The vastus lateralis muscle is the preferred site for intramuscular injections in infants due to its size and safety. The deltoid muscle is typically used for adults and older children. The ventrogluteal muscle is more commonly used in toddlers and older children. The dorsogluteal muscle is not recommended for intramuscular injections in any age group due to its proximity to major nerves and blood vessels, which poses a risk of injury or sciatic nerve damage.
