A nurse is caring for a client following a motor vehicle accident. The client develops a fever of 40.6° C (105° F), has a heart rate of 155/min, and a blood pressure of 70/30 mm Hg. Which of the following alterations does the nurse suspect?
-
Diabetic retinopathy
-
Thyroid storm
-
Metabolic syndrome
-
Hyperglycemia
Explanation
Explanation:
Correct Answer: (B) Thyroid storm
Thyroid storm is a life-threatening condition characterized by extreme hyperthermia, tachycardia, and hemodynamic instability (such as hypotension), often triggered by a stressor such as trauma from a motor vehicle accident in a client with underlying hyperthyroidism.
Why Other Options are Incorrect:
A. Diabetic retinopathy — This is a chronic eye complication of diabetes and has no relationship to acute fever, tachycardia, and hypotension following trauma.
C. Metabolic syndrome — This is a cluster of chronic conditions (obesity, hypertension, hyperglycemia, dyslipidemia) and does not present acutely with these findings after trauma.
D. Hyperglycemia — Elevated blood glucose alone does not explain the combination of extreme fever, tachycardia, and severe hypotension seen in this client.
A nurse is teaching a client about mixed insulins to manage diabetes. Which of the following statements should the nurse include regarding the onset of action and duration of these insulins?
-
"Mixed insulins have a uniform onset of action and a single peak, making it easier to predict changes in blood glucose levels."
-
"Mixed insulins provide a stable and continuous reduction in blood glucose levels with no peak action times to monitor."
-
"All mixed insulins start working within 15 minutes of injection and have a duration of exactly 10 hours."
-
"The onset of action and peak times for mixed insulins vary, requiring close monitoring of blood glucose levels throughout the day."
Explanation
Mixed insulins combine two different insulin types (typically a rapid- or short-acting insulin with an intermediate-acting insulin), each with its own distinct onset, peak, and duration. Because these components act at different times, the overall pharmacokinetic profile is variable and requires close, ongoing blood glucose monitoring to prevent hypo- or hyperglycemic episodes.
Why the other options are incorrect:
A. "Uniform onset of action and a single peak." — Mixed insulins actually have dual peaks (one for each component), not a single, uniform peak.
B. "Stable and continuous reduction with no peak action times." — This describes basal-only insulins, not mixed insulins, which do have distinct peak action times.
C. "All mixed insulins start working within 15 minutes and have a duration of exactly 10 hours." — Onset and duration vary depending on the specific insulin combination used; there is no single fixed timeframe that applies to "all" mixed insulins.
A nurse is teaching a client about the healing process after a myocardial infarction (MI). Which of the following outcomes should the nurse explain is the body's compensatory change following an MI?
-
Enhanced myocardial contractility
-
Increased conductivity of the heart
-
Regeneration of heart tissue
-
Decreased cardiac output
Explanation
Following an MI, the damaged myocardial tissue is unable to contract effectively, leading to decreased cardiac output as a direct physiological consequence of the infarction, which the body then attempts to compensate for through other mechanisms.
Why the other options are incorrect:
A. Enhanced myocardial contractility — Damaged heart tissue results in reduced, not enhanced, contractility following an MI.
B. Increased conductivity of the heart — MI often disrupts, rather than enhances, the heart's normal conduction pathways, increasing risk for arrhythmias.
C. Regeneration of heart tissue — Cardiac muscle tissue does not regenerate after an MI; damaged tissue is instead replaced by non-contractile scar tissue.
A nurse is teaching a client about a newly prescribed hyperpolarization-activated cyclic nucleotide-gated channel (HCN) blocker to regulate the heart rate. Which medication is the nurse discussing?
-
Eplerenone
-
Empagliflozin
-
Ivabradine
-
Furosemide
Explanation
Ivabradine works specifically by blocking the HCN channels in the sinoatrial node, which slows the heart rate by reducing the pacemaker current, making it a targeted treatment for conditions such as heart failure and inappropriate sinus tachycardia.
Why the other options are incorrect:
A. Eplerenone — This is a potassium-sparing diuretic and aldosterone receptor antagonist, not an HCN channel blocker.
B. Empagliflozin — This is an SGLT2 inhibitor used for diabetes and heart failure management, working through a completely different mechanism.
D. Furosemide — This is a loop diuretic used for fluid management, unrelated to heart rate regulation via HCN channels.
A nurse is administering a powdered medication to a client. Which of the following actions should the nurse take first?
-
Check the client for allergies.
-
Document that the medication was administered.
-
Mix the medication at the client's bedside.
-
Determine the client's response to the medication.
Explanation
Explanation:
Correct Answer: (A) Check the client for allergies.
Checking for allergies is a priority safety action that must be completed first, before any medication administration, to prevent a potentially life-threatening allergic reaction.
Why Other Options are Incorrect:
B. Document that the medication was administered. — Documentation should occur only after the medication has actually been administered, not before.
C. Mix the medication at the client's bedside. — While mixing the medication is a necessary step in the administration process, it should occur after ensuring the client has no allergies, and not before assessing safety information.
D. Determine the client's response to the medication. — Evaluating the client's response can only occur after the medication has been administered, not as an initial action.
A nurse is reviewing a client's current medications. The nurse should identify that nortriptyline belongs to which of the following classes of medications?
-
Tricyclic antidepressants (TCAs)
-
Monoamine oxidase inhibitors (MAOIs)
-
Selective serotonin reuptake inhibitors (SSRIs)
-
Serotonin norepinephrine reuptake inhibitors (SNRIs)
Explanation
Nortriptyline is classified as a tricyclic antidepressant, a class of medications that work by inhibiting the reuptake of norepinephrine and serotonin in the brain, and it is often used for depression as well as neuropathic pain management.
Why the other options are incorrect:
B. Monoamine oxidase inhibitors (MAOIs) — Examples include phenelzine and tranylcypromine; nortriptyline does not work through MAO inhibition.
C. Selective serotonin reuptake inhibitors (SSRIs) — Examples include fluoxetine and sertraline; nortriptyline affects both norepinephrine and serotonin, not serotonin selectively.
D. Serotonin norepinephrine reuptake inhibitors (SNRIs) — Examples include venlafaxine and duloxetine; while nortriptyline also affects both neurotransmitters, it is structurally and pharmacologically classified as a TCA, not an SNRI.
A nurse is providing care to a client who has Parkinson's disease and is having difficulty swallowing. Which of the following departments should the nurse plan to contact for a consultation?
-
Occupational therapy
-
Nutritional therapy
-
Respiratory therapy
-
Speech therapy
Explanation
Explanation:
Correct Answer: (D) Speech therapy
Speech-language pathologists (speech therapy) specialize in evaluating and treating swallowing disorders (dysphagia), which is a common complication of Parkinson's disease due to impaired muscle coordination affecting the swallowing mechanism.
Why Other Options are Incorrect:
A. Occupational therapy — This focuses on helping clients perform activities of daily living and fine motor skills, not directly addressing swallowing difficulties.
B. Nutritional therapy — While nutrition may need to be adjusted based on swallowing ability, dietitians do not treat the underlying swallowing dysfunction itself.
C. Respiratory therapy — This focuses on breathing and pulmonary function, not swallowing mechanics.
A school nurse and teacher collaborate about an adolescent who has a developmental delay about noticing a recent change in the child's behavior, noting that they have become disengaged in class, do not appear to have a group of friends, and make negative self-comments. Which of the following recommendations should the nurse present to the child's parents to address these concerns?
-
Recommend that the child be transferred to a different school.
-
Scheduling routine sessions with the school counselor.
-
Tell the parents that this is expected part of development in adolescent years and is not concerning at this time.
-
Engaging the client in an organized school activity such as a club or organization.
Explanation
Explanation:
Correct Answer: (B) Scheduling routine sessions with the school counselor.
Given the noted behavioral changes — disengagement, social isolation, and negative self-talk — connecting the adolescent with a school counselor provides consistent, professional support to address underlying emotional or social concerns and monitor the child's well-being over time.
Why Other Options are Incorrect:
A. Recommend that the child be transferred to a different school. — This is an extreme, premature action that does not address the underlying emotional or social concerns and could be disruptive without clear justification.
C. Tell the parents that this is expected and not concerning at this time. — This dismisses legitimate warning signs (disengagement, social isolation, negative self-comments) that warrant further evaluation and support, especially in a child with a developmental delay.
D. Engaging the client in an organized school activity such as a club or organization. — While social engagement can be beneficial, it does not address the deeper behavioral changes as directly or comprehensively as professional counseling support.
A nurse in an obstetric clinic is caring for a client who is experiencing a high-risk pregnancy. Which of the following supports the provision of optimal prenatal care for this client?
-
The nurse's years of experience in the field of obstetric nursing.
-
The number of times the client has been pregnant previously.
-
The relationship between the client and their partner.
-
The communication between the provider and the client and her support person(s).
Explanation
Explanation:
Correct Answer: (D) The communication between the provider and the client and her support person(s).
Effective, open communication between the provider and the client and her support persons is essential for optimal prenatal care in a high-risk pregnancy, as it ensures shared understanding of the plan of care, promotes trust, and allows for timely identification of concerns or changes in condition.
Why Other Options are Incorrect:
A. The nurse's years of experience in the field of obstetric nursing. — While experience can be beneficial, it does not directly determine the quality of communication and individualized care that supports optimal outcomes for this specific client.
B. The number of times the client has been pregnant previously. — Obstetric history (parity) is relevant clinical data, but it is not itself a factor that "supports the provision" of optimal care in the way that communication does.
C. The relationship between the client and their partner. — While a supportive partner relationship can be beneficial, it is not as directly tied to the provision of optimal prenatal care as effective provider-client communication.
A nurse is providing a presentation to colleagues on emphysema. Which of the following subtypes should the nurse identify as having a complication of pneumothorax?
-
Proximal acinar emphysema
-
Panacinar emphysema
-
Centrilobular emphysema
-
Distal acinar emphysema
Explanation
Explanation:
Correct Answer: (D) Distal acinar emphysema
Distal acinar (paraseptal) emphysema affects the distal portion of the acinus near the pleura, often leading to the formation of subpleural blebs and bullae, which are prone to rupture and are a well-recognized cause of spontaneous pneumothorax.
Why Other Options are Incorrect:
A. Proximal acinar emphysema — This is another term related to centrilobular emphysema, affecting the proximal respiratory bronchioles, and is not specifically associated with pneumothorax risk.
B. Panacinar emphysema — This type uniformly affects the entire acinus and is more commonly associated with alpha-1 antitrypsin deficiency, not specifically linked to pneumothorax.
C. Centrilobular emphysema — This type, most associated with smoking, primarily affects the central portion of the acinus and is not the subtype most linked to pneumothorax.
