Nokea
The client is being instructed on the proper use of a metered-dose inhaler. Which instruction should the nurse provide to ensure the optimal benefits from the drug?
- A. Fill your lungs with air through your mouth and then compress the inhaler.
- B. Compress the inhaler while slowly breathing in through your mouth.
- C. Compress the inhaler while inhaling quickly through your nose.
- D. Exhale completely after compressing the inhaler and then inhale.
Correct Answer: B
Rationale: To ensure optimal benefits from a metered-dose inhaler, the client should be instructed to compress the inhaler while slowly breathing in through the mouth. This technique facilitates the medication to reach deep into the lungs, allowing for an optimal bronchodilation effect. Option B is correct as it promotes the proper coordination of inhaler compression and inhalation, ensuring effective drug delivery. Options A, C, and D are incorrect as they do not support deep lung penetration of the medication, which is essential for its effectiveness in treating respiratory conditions.

The nurse is developing a plan of care for a client scheduled for an above-the-knee leg amputation. Which action should the nurse include in the plan of care when addressing the psychosocial needs of the client?
- A. Explain to the client that open grieving is abnormal.
- B. Encourage the client to express feelings about body changes.
- C. Advise the client to seek psychological treatment after surgery.
- D. Discourage sharing with others who have had similar experiences.
Correct Answer: B
Rationale: Surgical incisions or the loss of a body part can alter a client's body image. The onset of problems coping with these changes may occur during the immediate or extended postoperative stage. Nursing interventions primarily involve providing psychological support. The nurse should encourage the client to express how he or she feels about these postoperative changes that will affect his or her life. Option 1 is an incorrect statement because open grieving is normal. Option 3 indicates disapproval, and in option 4, the nurse is giving advice.
During a clinic visit, the mother of a 7-year-old reports to the nurse that her child is often awake until midnight playing and is then very difficult to awaken in the morning for school. Which assessment data should the nurse obtain in response to the mother's report?
- A. The occurrence of any episodes of sleep apnea
- B. The child's blood pressure, pulse, and respirations
- C. Length of rapid eye movement (REM) sleep that the child is experiencing
- D. Description of the family's home environment
Correct Answer: D
Rationale: When a school-age child has difficulty going to sleep and waking up in the morning, it is important to assess the family's home environment. This includes factors such as bedtime rituals, noise levels, lighting, use of electronic devices, and overall sleep hygiene practices. Understanding the home environment can help identify issues that may be contributing to the child's sleep problems and guide the development of a plan to promote better sleep habits. Options A, B, and C are less relevant in this scenario. Sleep apnea typically causes daytime fatigue rather than resistance to bedtime. Assessing vital signs like blood pressure, pulse, and respirations is unlikely to provide insights into the child's sleep patterns. Monitoring REM sleep duration is not practical in a clinical setting and may not directly address the reported sleep issues in this case.
A client is to have arterial blood gases drawn. While the nurse is performing Allen's test, the client states to the nurse, 'What are you doing? No one else has done that!' Which response the nurse makes to the client is most therapeutic?
- A. I assure you that I am doing the correct procedure. I cannot account for what others do.
- B. This step is crucial to safe blood withdrawal. I would not let anyone take my blood until they did this.
- C. Oh? You have questions about this? You should insist that they all do this procedure before drawing up your blood.
- D. This is a routine precautionary step that simply makes certain your circulation is intact before a blood sample is obtained.
Correct Answer: D
Rationale: Allen's test is performed to assess collateral circulation in the hand before drawing a radial artery blood specimen. The therapeutic response provides information to the client. Option 1 is defensive and nontherapeutic in that it offers false reassurance. Option 2 identifies client advocacy, but it is overly controlling and aggressive, and undermines treatment. Option 3 is aggressive, controlling, and nontherapeutic in its disapproving stance.
The nurse plans to administer diazepam, 4 mg IV push, to a client with severe anxiety. How many milliliters should the nurse administer? (Round to the nearest tenth.)
- A. 0.2 mL
- B. 0.8 mL
- C. 1.25 mL
- D. 2.0 mL
Correct Answer: B
Rationale: To calculate the volume to administer, use the formula: (Volume to administer = (Ordered Dose × Volume on hand) / Dose on hand). In this case, it would be (4 mg × 1 mL) / 5 mg = 0.8 mL. Therefore, the nurse should administer 0.8 mL of diazepam. Choice A (0.2 mL) is incorrect because it miscalculates the dosage. Choice C (1.25 mL) and Choice D (2.0 mL) are incorrect as they do not align with the correct calculation based on the ordered dose and available concentration. The correct answer, 0.8 mL, is derived from accurate dosage calculation and aligns with the formula for IV medication administration, ensuring the safe and effective delivery of the medication to the client.
The client with partial-thickness (second-degree) and full-thickness (third-degree) burns is at risk of infection. What intervention has the highest priority in decreasing the client's risk of infection?
- A. Administration of plasma expanders
- B. Use of careful handwashing technique
- C. Application of a topical antibacterial cream
- D. Limiting visitors to the client with burns
Correct Answer: B
Rationale: The correct answer is the use of careful handwashing technique. Proper handwashing is the most effective way to prevent the transmission of infectious organisms. Option A, administration of plasma expanders, addresses hypovolemia in burn patients but does not directly decrease the risk of infection. Option C, application of a topical antibacterial cream, is beneficial but not as effective as proper handwashing in preventing infection. Option D, limiting visitors, may help reduce the risk of exposure to pathogens but is not as critical as ensuring healthcare providers maintain strict hand hygiene, which is the cornerstone of infection control in any healthcare setting.
